1990 3sge Will Not Start

[jimbob1975]

Hi All,I have a big problem with my car at moment it was running perfect a while ago and it seems that when you leave it to go cold it will not start!

It seems to be electrical because I have checked the fuel pressure and that is ok, and I have pulled a spark plug and they are sparking ok.

It trys to splutter into life but dies as if no fuel is getting through!

The check engine light is on very faintly and if you put the ignition to the first position the temp gauge chucks a fit and moves to max and then back again!What is going on?

I have checked for codes and no codes.

Reset ecu.Its as if the cold start injector and the injectors will not open?

When the engine does stumble into life as soon as you try to catch it with the throttle it dies straight away with the check engine light flashing on?

Anybody have any ideas please???

Have you checked for a air leak in the intake after the air flow sensor

Hi Geezewayne,I have checked and there are no air leaks,could it be a sensor or something?Or even a relay?Thanks. :(
