Amjad Posted October 3, 2015 Share Posted October 3, 2015 (edited) Okay so recently the car has refused to start on 2 occasions.1) Following a service, primed the engine as normal. Went to refit king lead and EFI fuse, and tried to start the engine. Cranked over for ages but wouldn't start. Went away for a couple of minutes, making sure king lead was on properly, looked over earths etc. Then the car started?2) Was coming off the motorway after a 30 minute drive, hammer down on some dual carriageways before letting the car cool down for the last 5 minutes and parking up. Came back out and went to start the car an hour later and same thing again, cranked but wouldn't start. I thought maybe something had worked loose under hard driving so checked engine over and stuff looked normal. Then seeing as the ignition dash lights were on we decided to push the car to bump start it. 3) A related issue: I park facing uphill and occasionally when I start the car, it splutters into life and can struggle to have a normal idle until I give it a few revs. And then it settles down and drives normally. Ignition system is all new apart from the HT leads (which will be replaced soon as one is looking pretty sorry for itself).Started pushing and turned car around to point downhill, thought I'd try starting by the key once more and it started straight up. Wat.So yeah but confused now, I've read around and seen it might be due to a faulty fuel pump? Car is a '95 GT still on stock pump.Any help would be much appreciated!Amjad Edited January 7, 2016 by Amjad Quote Link to post Share on other sites
Socks Posted October 3, 2015 Share Posted October 3, 2015 Have you got an immobiliser or alarm on it? Quote Link to post Share on other sites
Calum122 Posted October 3, 2015 Share Posted October 3, 2015 My first thought was fuel pump. For the price if a 255lph walboro it's not a bad upgrade anyway even if it isn't that. Quote Link to post Share on other sites
Amjad Posted October 3, 2015 Author Share Posted October 3, 2015 It's not immobiliser/alarm stuff for definite, no dodgy wires or anything wrong thereIf it's pump then that should be an easy fix, just wanna make sure it's that and not something else Quote Link to post Share on other sites
Ollieh17 Posted October 3, 2015 Share Posted October 3, 2015 Battery connection? Mine always used toWobble loose. Then work again with the slam of the bonnet or minor disturbance Quote Link to post Share on other sites
Amjad Posted October 3, 2015 Author Share Posted October 3, 2015 Nah the battery connections looked fine as did the earths Quote Link to post Share on other sites
morgey Posted October 4, 2015 Share Posted October 4, 2015 Could be Engine earth. Clean all earth facea or Run a fresh one from block to chassis to battery to be sure. Its a cheap fix/upgrade and may solve your problem. Quote Link to post Share on other sites
funny onion Posted October 4, 2015 Share Posted October 4, 2015 My red GT does start first time sometimes. I usually just hold the starter on for a few secs, turn ignition off then try again and it starts. Weird. Probably coolant temp sensor or something on mine but not sure about yours 😐 Quote Link to post Share on other sites
JayJ Posted October 4, 2015 Share Posted October 4, 2015 My friend's scooby had the same kind of issue and it was fixed by new fuel pump. Quote Link to post Share on other sites

Its a cheap fix/upgrade and may solve your problem. What makes you think it's an earth? I don't have any spare wire/connections to make a new wire at the moment My red GT does start first time sometimes.

My friend's scooby had the same kind of issue and it was fixed by new fuel pump. That sounds promising, hopefully it's just that! One thing I just remembered, is another related issue: I park facing uphill and occasionally when I start the car, it splutters into life and can struggle to have a normal idle until I give it a few revs. And then it settles down and drives normally. Ignition system is all new apart from the HT leads (which will be replaced soon as one is looking pretty sorry for itself). I'll add that to the first post for anyone who hasn't seen the topic yet Edited October 4, 2015 by Amjad Quote Link to post Share on other sites
Flaminsam Posted October 4, 2015 Share Posted October 4, 2015 The engine coolant temp sensor can cause the engine not to start. If the ecu doesn't have a signal it may be putting too much or too little fuel in. Are you running a fcd at all? These can also interfere with the Ecu. Failing that the fuel pump could have a crap earth. The earth point for the pump is behind the drivers side rear panel in front of the rear strut tower. You can also try bridging out fp and b+ In the diagnostic port to see if the pump runs. Quote Link to post Share on other sites
Amjad Posted October 4, 2015 Author Share Posted October 4, 2015 ECU side just running a Mine's ECUI'll check that earth and try bridging the pump as I tested it a few months ago. Could it just be that my 20 year old pump is intermittently struggling to work? Quote Link to post Share on other sites
enots Posted October 4, 2015 Share Posted October 4, 2015 Got a spare standard pump down the garage your welcome to try man Quote Link to post Share on other sites

Amjad Posted October 13, 2015 Author Share Posted October 13, 2015 Make that 3 break downs! This time I hadn't driven the car that day. Again went to look around engine bay, nothing seemed awry. Went to start the car and it fired up on 2nd try Quote Link to post Share on other sites
H_D Posted October 13, 2015 Share Posted October 13, 2015 the last thing you want is for the pump to fail whilst the car is on boost Quote Link to post Share on other sites
Amjad Posted October 13, 2015 Author Share Posted October 13, 2015 the last thing you want is for the pump to fail whilst the car is on boost Yeah I've been taking it easy and just using car to get to/from uni. Do you reckon it's the pump too? Quote Link to post Share on other sites
H_D Posted October 13, 2015 Share Posted October 13, 2015 Even if its not the pump at fault its still worth changing it if your currently using a factory pump Quote Link to post Share on other sites
Amjad Posted October 13, 2015 Author Share Posted October 13, 2015 Yeah I agree, just hope this is what's causing my problems! Quote Link to post Share on other sites
Amjad Posted November 3, 2015 Author Share Posted November 3, 2015 HT leads and pump replaced. Car ran fine for a week and it's happened a 4th time now. I had to try about 6 times to get it started so this has been the worst one yet Quote Link to post Share on other sites
goldenvtr Posted November 3, 2015 Share Posted November 3, 2015 (edited) any fault codes? check the earth on the manifold by the idle valve.... wire bush both surfaces then refit. coolant temp sensor is a cheap replacment id try that next had a similar issue on my mx5 few years ago and that was the efi relay Edited November 3, 2015 by goldenvtr Quote Link to post Share on other sites
Idrees Posted November 3, 2015 Share Posted November 3, 2015 I agree with Dan.. Coolant temp sensor Quote Link to post Share on other sites
Amjad Posted November 3, 2015 Author Share Posted November 3, 2015 EML hasn't come on, can I still trigger codes if I do a diagnostic check? Cool I'll try that sensor next, thanks guys! That earth looks okay (earthing kit fitted a few years ago). The one on the wing has gone a bit rusty so that needs cleaning but nothing obviously wrong as far as I can tell Quote Link to post Share on other sites
Ep82gi Posted November 3, 2015 Share Posted November 3, 2015 When you put your foot down from say 2k rpm do you get a miss fire around 5k rpm or dose it feel like it's going to give up n cut out anything like that? Quote Link to post Share on other sites
