TrisK Posted January 29, 2014 Share Posted January 29, 2014 I hate these threads as they are so vague, but im getting a bit stumped. For people who dont like reading, key points are in boldWe have a GT, that we took the engine out of, and now its back in. Everything is visibly plugged in.Whilst it was out we removed some sensors, and relocated the battery to the boot.The battery in the boot is earthed to the boot catch.The sensors we removed are:1: The Panel of sensors above the ignitor2. The Termistor looking thing, that is in the light loom3. The sensor with two vacuum ports at the end of the injector/knock sensor wiringAll of which im pretty sure arent important, but just to mention everythingWE have fuel pressure at the rail, and it smells of fuel when trying to crank it.Also if we put a spark plug in the end of the HT lead then it sparks when earthed to the manifold. It sparks approx once a second. Is that too slow?The engine earth, there is only one, from the gearbox to the passenger side chasis leg. Although im sure it was like this before the engine came out and it worked fine.We definately have fuel at the rail, as we have pressure. but how can i test the injectors?

daniel_g Posted January 29, 2014 Share Posted January 29, 2014 There should be an earth at the driver side engine mount aswell.Just add a few random earth straps around the bay Standard earths are pish. Quote Link to post Share on other sites
TrisK Posted January 29, 2014 Author Share Posted January 29, 2014 There should be an earth at the driver side engine mount aswell.Just add a few random earth straps around the bay Standard earths are pish.Did that last night. Added 3 extra earths from around the block to the bay. still the same Quote Link to post Share on other sites
daniel_g Posted January 29, 2014 Share Posted January 29, 2014 Then you'll just need to do the usual checks until it runs lol, been there many times haha.Make sure the timing is spot onMake sure the starter is getting the correct VSpark plugs are clean/newCylinders arent floodedYouve a good batteryGood earthsSwap over injectorsAlong those lines anyway.None of the sensors you removed will affect starting.

Except check starter voltageand Check igntion timing (have adjusted on the 2 12m bolts, but need to tyr taking the distributer out and spinning it 180.im sure its something simple and stupid Just a nightmare, and i KNOW none of those sensors are important. but when you run out of options you start doubting yourself you know how it is. just frustrating Quote Link to post Share on other sites
TrisK Posted January 30, 2014 Author Share Posted January 30, 2014 Was up there again last night Checked Fuel PumpSTarter is fineChecked ignition timing PLugs are wet, we have fuel on all 4. It just wont go Quote Link to post Share on other sites
Socks Posted January 30, 2014 Share Posted January 30, 2014 If there wet you don't have a spark or a strong enough one... DO you have a decent spark on ALL 4 cyl's.... Try turning it over for a long period of time with injectors unplugged to clear the cyl of shite. (60secs+) Poor some fuel into the throttle body and try starting it without the injectors still plugged in... Quote Link to post Share on other sites

(60secs+)Poor some fuel into the throttle body and try starting it without the injectors still plugged in...The spark is a bit naff (its quite yellow) tried spraying brake cleaner in the inlet and it didnt seem to go Ive got a feeling is something to do with ignition Quote Link to post Share on other sites

Will rule out flooding it in this cold weather! Quote Link to post Share on other sites
daniel_g Posted January 30, 2014 Share Posted January 30, 2014 Swap the coil / ignitor over for a known good one. Quote Link to post Share on other sites
TrisK Posted January 30, 2014 Author Share Posted January 30, 2014 Swap the coil / ignitor over for a known good one.This is a known good one, as it started the car before we took the engine out. Will test it on my car tonight, as taking my GT there to compare tonightDo what I suggested...Will rule out flooding it in this cold weather!Will do it when i head back up there tonight Quote Link to post Share on other sites

morgey Posted January 30, 2014 Share Posted January 30, 2014 Earths on the back of the inlet mani. They're a common one to cause issues. Have to be mounted to inlet not anywhere else instead I've found Quote Link to post Share on other sites

morgey Posted January 30, 2014 Share Posted January 30, 2014 Naa there's a collection of about 4 small Earths that bolt on the inlet Iirc. Come from the main loom Quote Link to post Share on other sites

Flintygt Posted January 30, 2014 Share Posted January 30, 2014 (edited) That is the only earth on the inlet manifould and it is the only one it has had. Can you get picture off the other earths. Many thanks flint Edited January 30, 2014 by Flintygt Quote Link to post Share on other sites
morgey Posted January 30, 2014 Share Posted January 30, 2014 They be the ones, on the n/a they are around the tb area. I tried moving them and it didn't run lol Quote Link to post Share on other sites
Flintygt Posted January 30, 2014 Share Posted January 30, 2014 They be the ones, on the n/a they are around the tb area. I tried moving them and it didn't run lolYeah that's there. The inlet has been powder coated but checked the continuity and it's still a good earth Quote Link to post Share on other sites
TrisK Posted January 30, 2014 Author Share Posted January 30, 2014 Timing belt had slipped. Fuck knows how. But it hadRetimed it and it runs. Finally! Quote Link to post Share on other sites
daniel_g Posted January 30, 2014 Share Posted January 30, 2014 Glad its sorted can be easy to mis timing sometimes ;) Quote Link to post Share on other sites
TrisK Posted January 30, 2014 Author Share Posted January 30, 2014 Glad its sorted can be easy to mis timing sometimes ;)I'd checked ignition timing but not the actual timingNo idea how it moved as the engine ran when removed and we didn't touch the cambelt. Just chirping if runs againThanks for the suggestions lads. It's hard to diagnose a problem from hundreds of miles away Quote Link to post Share on other sites
