Hi everyone I'm new to the forum,..
I have a 01 monte that I recently changed plugs and wires in..a few days later it started running rough put a code reader on it turns out the EGR is stuck closed..i cleaned it out well to the best that i could..let it dry for 30 min..put it back in and it started up fine i got a text to go to work did what I had to do when I went to leave work it would crank but wouldn't start so I checked the battery the fuel pump its getting spark and has a half tank of fuel..but no start I'm lost..could sumone help me out and give a tip or two..pls thank you.

 

If youre sure youre getting fuel and spark, start checking the sensors on the TB. MAF would be the first I check, just unplug it and try to start the car.

 

If you've confirmed it is sparking, then you need to look into fuel. If it has fuel and spark, it will run. You've confirmed one, so it must be the other.

Check for fuel pressure and then check to make sure the injectors are actually firing.

 

ok I'll give that a try,..thank you veary much appreciated..ill let you know how it goes.thank you

 

To do so I will need to get a fuel pressure gage then..thank you I'll let you know how it turns out.

 

Should be able to rent one at your local parts store for cheap.

Also always the 'plan B' method of just poking the Schrader valve with a screwdriver tip wrapped in a rag to see how it comes out. If it just dribbles out, then obviously thats not to spec. Obviously a lot more dangerous spraying fuel in thr engine bay though.

 

Well I replaced the fuel pump and filter along with the plugs and wires..still doing the same..how ever I did spray sum stating fluid in where the mass air flow sensor is it sounded like it wanted to start but just gave enough to give me hope just to get back to square one..any advice..I've tried every thing everyone said to do..no luck!

 

I presume because you replaced the fuel pump, you found pressure was low / the original had failed? Have you confirmed it has fuel pressure now in spec?

Id mentioned to make sure the injectors were firing, what method did you use to verify that? Noid light?

Any differences at all with the MAF unplugged like whtmonte had suggested?

The fact that starting fluid makes it try to catch makes this sound almost certain to be a fueling issue (but we kind of already knew that since you confirmed it had spark). It's just very unusual if it has 100% fuel pressure and the the injectors are opening that it isn't getting enough fuel. Thats why I asked those follow up questions before we move to something else.
