Default Urgent help needed

ok here's the strory: I went to change out my fuel filter so I follow the instructions on http://www.scoobymods.com/forums/sho...=6239#post6239
except I reset the ecu before I changed it because I was going to change the air filter too but it was too big so I didn't.

Well any way I reconnect the battery and go to start the car which at first it doesn't want to start I figured this was reasonable after the change. on the 3rd crank it starts up but then i watch the rpm guage just drop and then it stalls. so I start it up again and same result.

I start it again then give it a little gas and it will stay running as long as I am giving it gas then dies out when I let up. What the hell did I do wrong? Would the air filter box not being on tight (although I think it is and shouldn't matter anyway) have anything to do with it? Any suggestions? thanks

OK, here we go.
1-Did you get a CEL?
2-Are ALL the plugs/lines reconnected?
3-Are all the intake parts reconnected?

I am guessing you did not get something together correctly and it is messing with the ECU.

Double check everything again.

Resetting your ECU should not have been a problem with any of it.

1.Nope no CEL, it wouldn't even stay on that long for me to see one

2. Yeah I only undid the 2lines that go to the fuel filter and put them back with the hose coming from the "rear" to the IN tube on the filter and the hose going to the "engine" to the OUT tube on the filter

3.It should be becaude I only removed the cover and pulled out the air filter then I put it back together just the 2 clips on the side and the 3 notches on the bottom.

My guess is that you did not refill the filter with fuel, so possibly air got trapped in your lines.
I don't know if continued cranking would push the air out through the injectors (or good for the injectors), or if you would need to bleed the system at its highest point.

Not really helping, just throwing ideas out there.

Try turning the key to 'on' a few times(maybe 3 or 4), which will kick the pump on. Each time, hold it there and listen for the fuel pump(a small hum) for about 5 seconds. Then turn it off, and repeat. After a few times, try and start the car and see what happens. This will ensure you have good pressure up front BEFORE you start sucking the fuel into the engine.

Turn the key to the ON position and wait 45 seconds. Then try to start it.

The fuel pump will run for a while even though the car isnt running. It might not have been up to pressure yet.

Also make sure the MAF (if you have one) didnt come disconnected

I was thinking that but I'm not sure what it is exactly and what it hooks up too I'm gonna try leaving the key in the on position thing. (cross my fingers)

OK never mind thanks for helping out the n00b. I finally saw the THICK hose that wasn't connected from the engine to the airfilter tubing.






To think I want to go to school for this

Yep, I've finally learned that lesson as well. Anytime you've been poking around under the hood, and then the car doesn't run right, check the vaccum lines/hoses. Nine times out of ten I've knocked something loose, or just forgot to reconnect it.

Speedwagon: I thought the pump ran for 60 seconds when the key is in the on second.

Glad you figured it out.
Also glad I had it covered in my post.

I was on my way to post this, but it looks like you got it. I did the same thing a couple years ago.
