SOURCE: Isuzu Hombre pickup, 2.2L Vortec, Won't Start.

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

SOURCE: '94 S 10 Blazer V6 Vortec EFI. Fuel pressure

your statement is fuel pump work ok, have you tested for proper fuel pressure. just because the fuel pump works it could have less pressure needed to start the engine. maybe the fuel filter is plugged. start out by replacing the fuel filter, if this doesn't fix it, you need to pressure test the pump. even 10 psi reduction in pressure will allow the engine not to start.

SOURCE: Engine runs extremely rough, seems to be fuel

Have you changed the plugs, if any are fouled out or if any are worn, it takes more to fire it under load and may be spark knocking because one of the plugs can't fire off all the gas and cause it to skip or idle rough.

SOURCE: 1999 chev blazer won't start new fuel pump

So, do you hear the pump buzz on, when key is on? If that's good, then check your ignition circuit: check for spark at a plug. Use insulated pliers, hold end of plug wire 1/4 inch form engine bolt or ground source. When cranked, you should see a bright blue spark. Yes? Try another plug wire, too. No? Try another plug wire. If you have NO spark, could be your coil, coil pack, crank position sensor, ignition module. I would recommend using a diagnostic flow-chart to go through the ignition circuit. That way, you are not replacing unecessary parts_Expensive! Of course, if you have spark at plugs, your ignition circuit is good! Then you have to look further, like your injector circuit. Good luck.

SOURCE: 1985 corvette cranks but won't

Check to see if you have spark, if you do, and still it does not start, then you may think that fuel is not getting to it. At this point, use some starting fluid and spray it at the throttle opening. That should start it for a few seconds and give you the answer.

Most vehicles do not have an oil drain plug for the tranny...you have to drop the pan to change the oil. Make sure you install a new gasket when you put it back on.

Just won't start! fuel pump ok, filter ok, psi ok, turns over just won.t start


You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, or a list of other things.
Even the fuel pump.
If this is a vortec V6 it takes at least 60psi to cover the injectors.

On the vortec engines they require 56 pounds of fuel pressure to start a few pounds shy of that you have a dead vortec you will need a fuel pressure guage to verify

You need to check the crank sensor, this controls tthe injector pulse. If it will attempt to start with alternate fuel but not on its own, it sounds like the injectors arent pulsing, so your not getting fuel. Try the crank sensor first.
