When you say itwon't start I'm assuming the starter is turning the engine over but it won't fire. If this is the case then you need to check to see if you have fuel pressure and then check for spark at one of your spark plug cables. If either one of these are missing car won't start. If both ar present then perform a compression test on all cylinders and checkyour readings this will help to tell you if you have any internal problems. Also if you have fuel pressure and spark check your injector circuits by unplugging an injector connector and hooking up a noid light (availeable at any auto parts stor tool section) see if it flashes while cranking engine, if it's good it'll flash rather quickly.

New fuel pump, two weeks later it wont work


If there is power to the pump, and it's not running, you have a faulty pump, and should be able to get a refund. Check your fuse and relay if there is no power.

1997 gmc jimmy wont start all the time


I had the same exact problem. After spending thousands on parts. It finally proved to be the CPI injector assembly. Change that and you're truck will be like a whole new vehicle. Most parts store sell a conversion assembly to MPI injection it's a much better desighn that the CPI. I was going nuts for a year chasing this problem. I hope this helps.
