I started my 3.4L the other day and immediatly shut it off because there were several things I still needed to do. Top off the coolent solder a couple wires in the harness etc....
So, here is the problem. I can start the engine and it will run for a few seconds maybe 5 almost sounds like its starting to idel right and then it just shuts off. It dosent seem to be ruinning on 6 cyl. Sounds more like 4 and it runs really rough. It does run though. Its not a misfire.
Keep in mind I could have multiple problems going on at the same time since this is a new swap. The plugs will get wet with fuel if I continue to crank it. I have to turn the key to the off or acc position or it wont start again no mater how much I crank it.
Here is what I have checked, am I missing something?
Coils OK within spec
plug wires tried two sets
brand new plugs (did the same exact thing with the old plugs)
Ignitor hooked to the correct coils
all grounds seem to be fine including the sensor ground
fuel system is pumping till well after the motor dies
If I step on the gas it dies even quicker (seems like a fuel problem but its got plenty of fuel)
Brand new MAF (starts and dies with or withought the MAF)
voltage checks out at the ECU +B and BATT pins
ignitors seems to be pulsing the packs correctly but my meeter cant read that short of a pulse
I know there isnt an issue with the nutal start wire because its starts , right?
seems like its running on only 4 cyl but I know I have the wires right I checked like 8 times.
What else am I overlooking?
Ive been so close for two days now
ANY help would be really appricated.
