mccartney11 Posted August 15, 2017 Share Posted August 15, 2017 My ep70 conversion was running perfectly on Saturday did a 700km round trip without any hiccups , now when I try start it it won't start , if I crank it over for a few seconds and unplug injectors it'll start and then when I plug injectors back in it'll run fine, it just doesn't want to start , plugs are soaked when I take them outTried a different coolant temp sensor and didn't adjust timing this few weeks when it was running perfect Anyone any ideas?

Calum122 Posted August 16, 2017 Share Posted August 16, 2017 Sounds like ignition if it's getting fuel. Is it sparking okay? Quote Link to post Share on other sites
mccartney11 Posted August 16, 2017 Author Share Posted August 16, 2017 Seems to be sparking fine, like it will run once it firsts after priming the cylinder with fuel or a spray of east start with fuel pump disconnected...it's wrecking my head here Quote Link to post Share on other sites

starletezy Posted August 18, 2017 Share Posted August 18, 2017 Faulty reg maybe Quote Link to post Share on other sites
mccartney11 Posted August 18, 2017 Author Share Posted August 18, 2017 I'll try it Quote Link to post Share on other sites
Stu Posted August 21, 2017 Share Posted August 21, 2017 Has the coolant temp sensor earth been wired to the load grounds rather than the sensor grounds by any chance? Its a common mistake people make when wiring them up. There are two seperate earth circuits, one for sensors/triggers and the other for load devices. Also what was the fuel usage like on the road trip? Have you had a wideband on it to see what the afrs are like? Whats the base timing set at? Quote Link to post Share on other sites
mccartney11 Posted August 22, 2017 Author Share Posted August 22, 2017 I'll double check that actually I'm not too sure on that one...fuelling was 100% put in 55 and did 700km so around 35-40 mpg No havnt had. Wideband on, will take it to an exhaust centre for an emissions check and see if they can show afr results aswel , base timing is 10 degrees btdc Quote Link to post Share on other sites
