My new '95 16 valve Sidekick has quit running. The CEL had not been working at all when I first bought the Kick last week. From day one I had a problem with it stalling while driving down the road. It would shut off like someone turned the key off. Then if you tried to restart it, it would turn over but not fire. After 5 minutes it would restart and run fine until it stalled again, a few miles later. My buddy thought for sure it was a fuel pump or filter, so I changed the filter first, no change, still stalled. I then ordered a new Denso fuel pump. While I was waiting for the pump to come, I pulled the ECU to have a look at it. It looked great, all the caps looked fine (no leaking or swelling), no evidence anywhere of overheating. So I put it back in. Then I pulled the instrument cluster to see if my CEL bulb was burned out. It was, so I put in a new bulb. I couldn't do a test start because I had already pulled the old fuel pump. Today the pump came in and I installed it. I put in about 4 gallons of fresh gas and turned the key, I could hear the pump running, I did this several times to get fuel back into the lines. Then I tried to start the car, it cranks, but has not fired up a single time. The CEL is on all the time now. I found the nag switch and switched it. I put in a paper clip to get codes, but all I get is the light is on all the time, no flashing. I have disconnected the battery several times to reset, but just keep getting the same results. CEL on all the time, no flashing, car won't fire. I have not yet checked spark or fuel pressure. Any ideas before I dig deeper?
