I have a 1998 s-10 pick up with a 2.2 liter that quit on the freeway, had a lot of body codes, bridged the security system but still wont start. I can hear it start to catch but no start. Tried starting fluid no start. Can hear the fuel pump working but do not have a fuel pressure tester. did a poor man's test and fuel only shot about 3 inches up. Compression is between 150 and 180. I do have spark. Any idea at this point would be great, this is my bro-in laws truck and he's driving mine till we get this sorted out.
A good parts counter person might have an idea of what fuel system parts fail such as mass airflow sensors and throttle position sensors. Of course first rule out the fuel filter which on an older S10 I believe was hidden at the front of the engine on the driver's side. Often what the parts a store has in stock is an indicator of what fails.

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

THE FUEL PUMP IS BAD.
if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.
and i doubt that you are seeing enough fuel pressure to run a vortec engine.
low fuel pressure equals a non running vortec

My truck did this after I replaced the fuel pump. Turned out to Fuel Pressure Regulator. It would crank and crank but never start. It's located underneath the black plastic manifold on the side of the injectors.

Hi, is it possible the new timing belt was not set tight enough? Seems like your valve timing has slipped.

Hi Karl Sheehan, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box?
Ok Allen Eaton, What do you need to Know?
He changed the fuel filter about 2 weeks ago because the truck was lugging and backfiring that didn't help. I suggested the Crank Position sensor so he put a new on of those
Then it quit. A friend put it on a scanner and that's how we new about the body codes for the security, he also said codes came up he never saw before, additionally stated that he never saw so many codes come up. My bro in law said the truck started acting up a few months ago when the place he was driving for was flooded and he had to drive thru 18" to 2' of water to get to his Semi, quite a few times apparently.
