Okay, Heres the deal. I've had my 90 SHO for about 9 months, hasn't run properly EVER. I finally think I've got the thing fixed up, Start it, and it idles at 200 RPM, then stalls. Now it won't start. I'm getting fuel, Don't know if I'm getting spark or not, but I think it's the Crankshaft Position Sensor. Anything else the Guru's of the board suggest to check before I have it hauled to a shop to change the Sensors, Cause with my luck, that won't be it.

Well technically if your getting fuel your getting spark. But you should check if your getting enough fuel pressure.

Possible IAB/IAC? Does the tach move while its running/being started? Have you tried giving it gas while starting it to see if it will kick over and run?

 

[benharper]

gave it gas while starting it, no luck. Haven't watched the tach.

 

[ohfosho]

well tell us what u touched while trying to fix it the last time. and what it was doin before that.

Pull codes? If its a sensor thats making it run like that then it will trip a code.

 

[benharper]

Gonna pull codes when I get a chance. I gasket matched the intake, put on silicone hoses and connectors, put new valve cover gaskets on, and put new plugs and wires on (I already checked firing order.)

200 rpm idle and pressing the gas doesnt do anything, all the while it sputters, sounds like you need to check the pressure at the rail at 'key on'. You should get 30-40 psi. When my pump went bad, I was getting 10 to 15.
