2k brick wall

[element6]

Is it bad that I was hoping this thread would be about someone R3V-ing a car worth $2k into a brick wall?

I was hoping to see the same thing :(

Anyways, to the OP - My '87 vert just did about the same thing and it ended up being the rubber gasket ring that seals off the in tank low pressure fuel pump and fuel level sender unit.

Check all of your fuel lines, FPR's, fuel pump, etc. Remember there is also a FPR under the hood along with your feed line and return line. There a vac line that gets hooked in to that and it may need to be changed. (I think this is correct on a late model car, but mine is early model so I can't say for sure)

Also make sure you check that rubber ring that seals off the in tank fuel pump and sender unit!

I'm not saying that it couldn't be the CPS.. but the fuel system is a little easier to troubleshoot than them. Start with fuel.


In the days before I changed out my rubber ring and in tank low pressure fuel pump with a TRE340 (bypassing the external fuel pump) I was having fuel cutouts at completely random times. I could be on the highway doing 65 and go to speed up from the speed I was already maintaining by foot, even just slowly without mashing the gas, and my fuel delivery would suddenly cut out making it feel like I had hit a brick wall.. the front end would practically take a dive after I sped up for a split second and then hit that brick wall.

It didn't matter whether I hit the gas slowly or floored it, either way would lead to brick wall syndrome.. lol. The only cure was to get off the gas until I was giving it less gas than needed to maintain my slowing speed. At that point I couldn't speed up any further. I could only go slower or push the clutch in and rev the engine to whatever I wanted. Anyway you put it, the car couldn't hold it's speed under load from that point.

Usually, pulling the car over to the side of the road and letting it sit for a minute, then starting back up was enough to get me moving until I got it to my garage. I was also able to successfully turn off the engine while I was rolling on the highway, let the tach do its final twitch as the power left the ECM, then restart the engine and I would suddenly have power again.

I believe it was just because of the lack of vacuum in my system.

Hope you figure it out.

Thanks for all the replies everyone. Im going through the fuel system piece by peice and Ill let you know what i discover
