Ok I have changed the cap , rotor, wires, plugs. checked fuel pressure 60psi at all times even when misfiring, have not been able to check the cat convertor where can i go next to check components and fix this i miss my chevy
I now have a fuel pressure test gauge but not sure where to fit it and a new fuel filter if si required
also when driving starts off ok but when accelerating bogs down . Have checked EGR , new plugs wires and rotor and cap what to do next
Was turning over and starting fine. Next time I went to start it, it acted like the battery was low and would barely crank over. It wouldn't start. Made sure the battery would charge and even got a new battery. Still acts like the batter is low and cranks very slowly. Won't start. Help?
After rain the van will not start unless I place a hair blow dryer under the hood pointing towards the back

Bought this 2002 a couple months ago. It was leaking a bit but now it leaks like a sieve.
My back door window hatch lock stopped working. so I replace the fuse and now when I replace it it sparks and burns before i get it in. now the door locks only work with remote access key chain. and some times when the fuse is put in and works the door locks electric mechanism keeps going on and off till the battery runs down. I also noticed when I do get the rear door window hatch to come up water pours out the corners. is this a common problem? are these vehicles known for this? can it be fix easily or inexpensively?
Driver's side door handle replacement. Suggested solution above!
When you are all ready in drive and you start start off from a stop.Until you reach steed above 55 to 60 miles an hour.
yesterday I put $25 worth of gas using a different pump than I usually use. After driving a little over 20 miles van started sputtering, bucking and trying to stall. Pulled over and put scanner on it (yes I carry a scanner) threw code P0300. Van was running fine before gas fill had driven about 15 miles before before stopping at station. Just passed the emission 3 weeks before. Suppected water in gas put Heet in tank and had van towed home. Plan on checking for water when it stops raining today. My question is what else could it be that van runs fine then like flipping switch starts to misfire.
Won't drive forward nor backwards and brake pedal will hardly push
I have checked the fuses under the hood and behind the brake pedal, but do not find one labeled power locks. Everything else works fine.
Where would I find this switch and how do I fix the leak?
