Has spark on #1 cylinder & good fuel pressure measured at pump, no error codes, except a low coolant temp in history. Cranks until engine almost running while sprayed starter fluid in intake. Had small backfire pop a couple of times. What should i check next
SOURCE: not starting!
Check and see if the Injectors are firing. Disconnect one of the injectors and use a test light and paperclip. Put the paperclip in one of the disconnected injector connectors terminals, clip the testlight to the paperclip. Now touch the tip of the testlight to the other terminal in the same connector DON'T LET THE TWO TOUCH TOGOTHER AT ANY TIME!! Have someone crank the engine the light should blink if so good Now do it to the other three I have seen a bad computer that was only firing two injectors,
If its the computer you cannot just go and buy a used one and pop it in they are programmed to the vehicles VIN # you will go to the Chevy Dealer to have the program uploaded into the PCM in the truck
Please give me a fixya f you think this information is helpful Thanks Randy

have you checked all ofyour fuses? usually when you hook up a battery backwads you end up blowing a fuse and or fry your alternator on older modeled vehicles as there is no protection for it.
SOURCE: I have a 2000 / s-10 pick-up what is the fuel pressure
fuel pump issue. Soon it wont run at all. Fuel presure should stay consistant with key on.
6 cyl 60 - 66 psi
4 cyl 41 - 47 psi

SOURCE: engine turns over strong but wont start
one answer is lack of compression in the cylinders,normally associated with high miles.
could also be valve seats/spark plug gap/dirty air filter,there are a few more but start with the cheapest to diagnose and work up.....
