the heat is killing my car

it gave me a lot of trouble today, but with the new starter, itll crank after it dies which gave me a big clue on whats causing it. i was able to play with it a bit. after it died, i waited a few minutes. it would start back up but idle poorly. it had about 20lbs of fuel pressure. it kept wanting to die so i would give it more gas to keep it around 2000 rpms. over time, i kept having to give it more throttle to maintain 2000 rpm. eventually it couldnt maintain it tho and then died. it looks like the fuel pump... ive sure gone thru a lot of walbro 340 internals... ill have to replace it soon with an external of some sort.

All the new Walbros are failing. There supplier switched and is apparently sucking...
 
I've ran a Bosch external pump since 1992. No problems, more pressure/volume than this motor will ever use. Got it from Hahn racecraft out of Yorksville Ill.
Don't know if they still have them, they probably have better stuff now.

You are talking about the Bosch 204 but that still uses an internal pump...so he will need to find a reliable one.

I had the same problem with my TTA. It turned out to be due to the typical GM wiring, which builds up resistance over time and eventually does not carry enough amperage to kick the solenoid in. M.A.D. Enterprises carries a kit to fix the problem, which is basically a Ford solenoid that requires much less amperage to kick in. I installed the kit in my car, and now it starts hot or cold, summer or winter. Cheap solution. Call Mark at M.A.D. Enterprises (www.madelectrical.com) 559-539-7128. If you are adverse to putting a Ford part on your car, there are other ways to more directly wire it. I read about one in this forum, but don't recall exactly where. You will have to hunt for it, but the answer is out there.
 
i am more inclined to believe its the fuel pump due to the fact that its a newer walbro pump and people have been having problems with them, along with the fact that this is around the third pump ive had to replace. they work fine for a while, then go kaput. ive ordered an external weldon pump that should get here next week, im betting that solves it.

How do you plan on plumbing it? Are you getting rid of the intank and then just looping the hoses out to the external?
 
well i shouldnt have to remove the internal pump. im gonna take it to the place that replaced the starter and have them do the install on the pump. this is all getting expensive... i just took my car to get it inspected and the right rear tire is just a bit too worn for them to pass it... so, i get to buy new back tires now. this is all getting quite a bit more expensive than what i had planned for :whistle:

How are you going to plumb it then? Either you remove the internal pump and just have the external or you will have them running tandem which requires two good pumps...
 
ill have to check with the guy around here that works on a lot of the GNs and TTAs in the area... once the GN is ready ill pick it up and drop off the TTA.
 
they dropped the fuel tank today and found a ton of "tobacco-like" sludge inside. they also said the fuel sock on the pump was 3x too small. that makes me wonder where all that sludge couldve come from, and why the shop that installed the pump would put such a small sock on the thing... so instead of fabricating an external setup we are going to try another walbro 340 with a bigger sock and a clean tank. hopefully that will clear this up.
