Got some new lines. Got it all sorted out. It doesn't leak from the main line at the fuel filter. That'* good.

I think it'* one of my return lines has a leak in it now. This sucks.

Got all the fuel issues sorted out on this car.

I also replaced the ICM and spark plugs and the wires today. I still have this issue.

ive seen alot of 3.1s with that problem but never seen an actual cause of it...sorry

these kinda issues always seem to pop up with the older cars that have "low miles"

and to think im looking at a 20 year old cutty with the 3.4 with only 52K miles..imagine the issues on that thing

It'* still a car. I hope I can get this figured out. Maybe if I just keep throwing money at it that might help.

Tomorrow I'm going to pull the injectors test them find out what ones are bad. Replace those. The others I will flush. Maybe that will fix it.

The TB has been pulled and cleaned. I also got a new gasket for it. This car doesn't have a maf. I did replace the IAC.

I'm going to get a new EGR gasket and while that'* out I'll clean out those passages.

After I put the new pump I tested it. Key on (engine off) was 44 PSI. Engine running was 39. That'* normal to drop 5 or so PSI with an engine running.

Not sure my problem is that.

^ That was when I still had a bit of a leaky line. Now that that is fixed I bet those numbers are a bit higher.

I think a bad MAP sensor was causing this. Even though I didn't have any SES light. I unplugged the sensor and the car runs great. I plugged it back in and I had problems again.

So I'll get one tomorrow.
