Lately, whenever I try to start the car. It never catches the first time. It turns over, I stop, and when I turn the key the second time. It fires right up. It started doing this about 2 weeks ago now. I just now figured that this may be tied in to why the car randomly bogs down when I'm tryin to accelerate.

Has anyone else dealt with this? Any info?

Changes made recently..

went from pacesetter lts and ory to.. stock manifolds and cats. the car has a smog tune.

New plugs
New fuel filter
I cleaned the maf

I don't know what it could be.

 

Fuel system. Try turning on the key, count to 3, turn the key off then back on and see if it starts right up. If it does then you have a fuel system problem.

 

Found the problem in 15 min this morning.

Connected fuel pressure guage onto the fuel rail. Powered up the pump, and the pressure went up to 26PSI and immediately dropped off. I opened the access hole that I cut during my Walbro 340 install.

The fuel line on the pump was completely swollen and disfigured. It had small hole towards the top, and the clamp on the top had started to cut into the line.

I went to Napa and purchased some high pressure / fuel injection hose. $16.99 for 24".

After swapping out the bad line, powered the pump up. 54 PSI and it held steady.

The car runs strong as hell now. We scanned the codes before repairing the pump, and the were P0171 and P0174 if I remember correctly.

Thanks for all the help.... The Z is alive once again..
