My 1999 GMC Sonoma 4.3 engine just all of a sudden cut off with me , no warning at all and no engine light came on. I replaced the fuel pump and filter, distributor cap, rotary button, EGR valve, vacume hose to the ABS, new key. It cranks and only runs 10 seconds and just cuts off. What do I do next ?
No, I didn't think you could check a code without the light coming on ?
How do I do that or should I just get a new computer?
I noticed a coil wire was rubbing against another wire, I moved it and it cranked right up. I drove it up the road and back, what bothers me most is why the light did not come on.
Thank you for your time
