(FD) Car won't start. Electrical problem, other?
Hey Guys,
I'm really stumped, and I'm never usually stumped so I think this is a strange one. Basically the Stealth will not start, even after a fresh engine with 7bar of compression on each rotor face when cold and not run in!
Here is the story so far, I'll try to keep this as short as possible...
Last month the Stealth (FD) just wouldn't start after washing her. Car combusts when you turn key, but as soon you apply throttle it simply cut out.
Checked for spark, resistance of coils, CAS, injectors, flooding, fuel pressure was 43psi base etc and they were all fine.
Compression was very low, 5bar on rear rotor and 4 bar on front rotor from cold(engine has done 65k miles), tried tow starting and it combusts when in gear, but didn't sound "loud" as it would and died as soon as put clutch in.
Anyway we rebuilt another engine as it needed doing anyway and dropped it in. Car started first time and with a little help of throttle it eventually stabilised and sat idling on axle stands for 30mins up to full temps, at this point engine sounded fine(exhaust note etc) and rev'd freely.
Put all the intercooler pipes back on and took it off axle stands and started it again, went to reverse it out of the garage and it cut out. Then it started doing the same thing again with the other engine, started but cut out with any throttle at all!
Last thing we did that night was change the map sensor for another one and woots got the car started with 1/4 throttle while turning key. It ran really rough, engine shaking a little and the exhuast note is really subdued, the wideband is saying it is very lean above 16.5afr at idle and after that we drove round the block and put it back to rest.....as it was late, fuel pressure was 40psi base with a new aeromotive fpr.
It now doesn't start at all, you can hear it trying to fire up and it definitely ISN'T flooded and we did a comp test last night and all is well with new engine. As far as I can see there are no air leaks or cause for air leaks.
So if anyone can shed any light please post ahead. Any ideas welcome, however dumb you may think they are, i'll just post up in reply saying whether I've already tried it or not.
Ta,
Paul
