nick956 Posted December 16, 2014 Posted December 16, 2014 So I recently acquired a 99 sonoma and it doesnt not start. There is fuel going to injectors as we tested the pressure and it read 60psi. There is spark going into and out of distributor. My battery is good reading 13.1v. Compression is ok (like 80 psi or so)and has. The problem the previous owner had was that it shut down on him while driving and never started back up to running just cranked and cranked. I already replaced fuel pressure regulator, distrubutor cap, ignition control module checked out good and replaced the coil new. Also it wont ignite even if I put starting fluid into TB. Please help as im at a lost here with this stupid truck.
thewhitestallion Posted December 16, 2014 Posted December 16, 2014 crank sensor might be bad. if the crank sensor is not within it's threshold it will not let the truck start. is there a CEL?
nick956 Posted December 16, 2014 Author Posted December 16, 2014 Thats another thing, a cel is not on and the battery was dead before so since it has started . I even scanned the transmission and engine modules and no codes

NitroCherokee Posted December 16, 2014 Posted December 16, 2014 So if you spray starting fluid directly into the TB and it still just cranks? Like no fire at all? If that is true you have no spark. Even if compression was really low with starting fluid in there is you had spark it would at least makes some noises and "speed up" the cranking
nick956 Posted December 16, 2014 Author Posted December 16, 2014 Yes I spray and still no start. But I checked distributor and spark is going into and out of distributor and all the way to the plug . And yes it kinda sounds like it spins faster.
grampadirt Posted December 29, 2014 Posted December 29, 2014 Could be the fuel injector module,AKA spider.
