Subject:      My fool injection

I have had several people tell me that I should leave the FI on the bus. But last Summer when this problem arose, I got the FI motor and put it in, I spend weeks trying to get it to work correctly. No one knew what the problem was. I just want a bus that runs good. I would rather have the FI if I can get it working.

Last summer no one on the list knew a fix. Well now that the list has grown mabey someone with the fix has arrived.

Heres the scoop.

Last winter I took the bus, a 70 with a 1.7L in it (I didn't put the motor in it it can that way. for really cheap) on a ski trip. Outside temp didn't exceed 5 degrees F. n It was running quite well on that way up. When we tried to get it going to cone home she didn't want to start. 30 minutes later and with some numb fingers she can alive. Although she sounded sick. Got hope, barely. Turns out I lost two valve seats on seperate cylinders. remedy rebuild or replace.

Well I wanted to put a larger motor in and I did actually want FI on it. I had just spent the last several months building a fuel injected motor for school, so I oight have had a little to much confidence.

Our buddy Bill Calspy (sorry about the spelling) in Cleveland had a 2L to unload. So over spring break I took the trip to visit Bill. I live in DC. I got the motor and rebuilt it. From there it went down hill.

Let it be known that the same motor and FI system worked in Bill's bus. I watched him drive it into the garage before we yanked the motor. Now almost a year later the bus is still parked. I bought another VW for daily driver.

The probelm is that when the ignition is on the injectors open and stay open. no pulsing. The injectors are not grounding where they shouldn't. Checked that. I am getting a good siginal from the coil. Wires are hooked up correctly. Checked several times. Air flow meter was tested and is OK. Double relay is also OK. Grounds are good, connected as in the manual. I even replaced the Brain box. No effect. Cylinder head thermo is OK as is the air temp sensor. I don't know what else it could be.

I would like to fix it, but I just want my bus back and running. If I can get it working I will have to put carbs on, or mabey an after market FI system, I have had better luck trouble shooting them.

Any solutions, fixes, or suggestions are greatly appreciated.
