Are you getting fuel?

[yellowevo82]

yes i took off the fuel feed line and it was gushing out..

[yellowevo82]

anybody?

[yellowevo82]

crank sensor and cam sensor are new, i have fuel..

[Adam@MMS]

Either the ECU is telling the coil to fire or it isn't. If it isn't then something is wrong with the cam or crank sensor input, I don't think it could be anything else, at least I can't think of anything else sensor wise. Pull up a wiring diagram or two on AllData maybe. I assume you checked fuses. If the immobilizer code in the ECU isn't right it will not fire. That's all I got. Better than nothing.

Are the injectors firing?

[yellowevo82]

took the spark plug out grounded it and im getting no spark.. spark plugs smell of gas so i assume yes there firing.

I had this problem once with my DSM. So I put the charger on the battery for 15 minutes and all was fine.
