I'm sure you've figured out your problem by now but for others with the same symptoms. One more thing could be a clogged catalytic converter/muffler. Even though it is not as common as it was when cats were first mandated and new engines running so clean. With all driving being "in town" where the engine does not get to op. temp during the daily comute it is still a possiblity. Also I'm sure you checked air filter but I didn't see it mentioned above. And with the fuel press regulator, before condemning it ensure it has a good source of vacuum.

SOURCE: firing order, 1990 Pontiac Grand am 2.5 l, 4 cyl

Its 1342 or 1432 To guarantee correct firing order take plugs out and place your finger/thumb over the plug hole so you can feel the compression cycle.Have some one flick the key on and off slowly .As soon as No 1 has done its compression cycle the next cylinder to compress will be in the firing order.You only need to test 2 clinders to tell you which one of the two firing orders ive given you.good luck and let me know how it goes

SOURCE: I have a 2001 Pontiac Grand AM SE, 3.4 Liter V6

I have a 2000 Pontiac Grand AM GT with 147,000 miles. A couple years ago it was sluggish going up hills and the engine tachometer would jump. The dealer found nothing wrong with the fuel injectors. I use STP injection cleaner at every oil change (5,000 miles Mobil 1 synthentic). The heater was also not getting hot enough... It was warm at best. So, I had the dealer change the theromstat at cost of slight more than $200. For whatever reason the sluggishness and engine tachometer jumping issue going up hill disappeared and has not come back since. The dealer said that the theromstat can mess with a lot things. It's worth a shot.

SOURCE: firing order of a 2001 pontiac grand am

Firing Orders General Information NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

2005 Pontiac Grand Prix won't fire at plugs or distributed cap


My info doesn't show a distributor on this vehicle, it shows a coil pack. I guess I can't help you?
Usually if no spark at the spark plugs, I also check for fuel injector pulse. If you have neither one, I check for rpm signal and or security system issue.

No Start


The next thing to check is if you are getting power and a ground pulse to the injectors.

2001 jeep Grand Cherokee fuel injectors


check the injectors on that bank for pulses.. a regular 12v text light will do it should flash when cranking... its very possible that the crank sensor or camshaft sensor on the replacement engine is bad and giving you all the problems you have now.. are you using the original injectors? if you have injector pulses then check the coil for pulses the same way.. btw make sure you have 12v to them even before cranking engine could be a bad asd relay..wet plugs on one bank would also indicate a possible leaking injector and basicly draing the fuel starving the oposite bank for fuel.. to verify that the rail must be lifted by removing all 4 bolts make sure the clips hold the injectors firmly and turn the key to run but dont crank it then look for fuel leakin from bottom of injector(s) any drips is a bad injector..
