85 golf fuel injection problems

I have a 85 golf gl 2dr with 1.8 8v 100 k MI on it. changed the fuel filter fuel pump is pumping good pressure to to inlet and cold fuel line, sealed cracked air tube.new coil strong spark, cleaned air flow plate seemed to move with no binding. probly sumpin stupid. any help many thank you's.

What problem are you having?

I had the same problem 1000 miles ago it ran for 5 minutes. then it seemed to be starving for gas. and finnally stopped i changed the filter and it ran fine. this timei changed the filter, cut the old open it had black discolorization, nothing serious. i have fuel at the fuel distributer feed and return and test port. with good pressure havent stuck a fuel pressure gauge on it yet. is there any problems inherent with cis-e fuel injection. I know its got a lot of miles on it but its so fun to drive.

Is that a CIS or CIS-E? The easiest way to tell apart: CIS-E would have a silver fuel distributor, CIS would be black.

its a cis-e fuel distributor.

Interesting, I haven't seen any CIS-E systems on non-GTI's. Since it seems to run for a few minutes then dies when it warms up, I'd start with the coolant temp sensor for the injection. It's located on the underside of the housing where the upper radiator hose goes into the cylinder head (blue connector). Resistance across the sensor pins should be about 2500 ohms @ 68 degrees F. Higher resistance at lower temps (e.g. around 4000 Ohms at 32 F) and lower resistance at higher temps (e.g. 200 Ohms when hot). They're not too expensive, so if you just decide to just replace it make sure you get the temp sensor for the injection, not for the temp guage in the dash. If the temp sensor seems okay, then you will probably need a special fuel guage set for testing CIS systems, and it gets complicated quick. Your fuel pumps can be running but not generating proper pressure, you will still get fuel at the distributor, just not the right pressure. Stalling out after the pump gets hot is not uncommon, does the pump noise sound different after it warms up?
