I picked up a 88 vw cabriolet. Was running rough wouldn't go over 50. Been working on it and cleaned up fuel injection. Was very dirty. Then it ran much better till a pump died or something. Replaced the sending unit then it would start good but only run for seconds and die. Then I replaced the main pump under the car. Now it won't start. Took the accumulater off and I think it's good. So there is no gas going to the filter in the engine bay. No pressure but two new pumps. Coil? CPR? I'm stumped.

have you checked fuel pressure regulator.hopefully this helps

Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

Hi. This is more of a fuel filter issue than a pump issue although, a bad fuel filter will eventually destroy a fuel pump. When the filter is restricted or clogged, this will tend to work the pump harder than normal. this will over heat the pump, therefore, shortening its life span. I recommend replacing the fuel pump and filter and, adding a fuel additive like techtron fuel injector cleaner/water remover as well.

Please rate and have a great day:)

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

Sounds to me like the fuel pump is worn out. They DO wear out. And even though they seem to be working, the brushes in the electric fuel pump may not be contacting all the commutator, thus making the pump weak. It may start the motor but can't maintain normal running pressure (27-35psi). Have you run the car out of gas shortly before this problem surfaced? If you have then it's your fuel pump. It was damaged when the tank ran dry. Even though the pump may seem to be working, it's still badly damaged and needs to be replaced.
Just as Matmenzies has stated, get a fuel pressure gauge and test the pressure. I'd start with a complete check of all your vacuum lines. Check for cracks on the vacuum hose that connects to fuel pressure regulator on the fuel rail. Also, if you can, get a hand operated vacuum pump to check the regulator. If you can place a vacuum on the regulator and it holds, I'd say move on the fuel pump and check it.
BTW, if the fuel filter has been changed, you may want to check to see if it was installed backwards! Some fuel filters are valved and will cause symptoms like this. However, this is an immediately noticeable mistake and you haven't provided enough info for me to say more. I'd pull it and check that it has any flow at all. You could have sucked in a big dirt ball and blown it right into the new filter, effectively stopping fuel flow. Then I'd blow out the fuel lines, just to be sure.
Start with these 2 things and post what you find. We'll go from there.
