Hi All, my 1988 245 is not starting and I am completely baffled. Apologies this will be a little long.
It was running fine last week. I pulled into my driveway one night and parked...it had been running fine. The next morning, I went out and turned the key. It turned on for about 5-10 seconds but was running very rough with no throttle response and then died. It hasn't turned on since.
It has spark at the coil and all 4 wires. The injectors fire - I used a noid light on each one. I found that the intank fuel pump was not running and had since replaced it. I can now hear both pumps run when I jump the fuses. I took the cover off the fuel pump relay and can see both contacts close when I crank the engine. I get power back at the intank pump, and that all seems to be working.
I pulled the fuel return hose from the fuel pressure regulator and attached another hose that ran to a bucket and cranked the engine. Ample fuel seemed to flow when the engine cranked. I replaced the fuel pressure regulator with another one that I had, thinking maybe it was flowing straight through (and I do not have the correct fittings at the moment to attach a pressure gauge). Nothing changed.
I did many of these tests with the Air Mass Meter unplugged, to keep that out of the equation.
I checked the timing belt and everything seems to be aligned, so I do not think it has jumped teeth.
At this point I can't think of anything else that could be causing it to not turn on at all. Any ideas would be greatly appreciated. Thanks in advance!
