Chevrolet Repair: gmc truck help please, gmc truck, car wash

Question
I have an 88 gmc 350 it was idling at the car wash I went to leave and it died and will not start again. I have already replaced the tps and checked all the plugs and it is getting gas, what is wrong?

Answer
Hi Rick...well you were at the car wash so that would tell me you need a tune up...check cap, rotor and wires....ign module and coil...even though you are getting fuel do you have enough pressure, ign system would seem to be your problem...hope this helps
