'86 22re starting problems
I have an '86 4wd p/u with the 22re, 137,000 miles. It runs like a top
but the initial (cold) start takes multiple tries. It will cough and
sputter, and stall for the first 2-4 attempts to start, then suddely
will kick in and as soon as it warms up a little it is good to go from
there on out. Once warm it will restart no problem. I suspected the
cold start injector or time switch, so I replaced them. However, I live
in AZ and a "cold start" right now is in 85 degrees. I would think it
would be able to start in those temps without the CSI. I tried jumping
the fuel pump test connector with the CSI removed from the intake
manifold so i could see if its flowing fuel and it isn't, but I think
it's too warm and it probably shouldn't be. Should it? The fuel pump
is running and there is fuel under pressure coming to the injector. The
resistance values for the injector and switch check out. When it was
colder out (60 Brrrrrr) I was having times when it wouldn't start at
all. It would just crank. Once it warmed up in the afternoon it would
start just fine. It's almost as if there is no fuel at the engine until
you crank for a while. I did try jumping the test connector for the fuel
pump, let it run for a few seconds and then try to start. it didn't seem
to make any difference. Sure does sound like a CSI problem doesn't it.
Recent work has included a new TPS which failed. I replaced it and set
it as per the fsm instructions and it seems to be working fine. The
timing chain was replaced. New alternator, thermostat, water pump,
belts, hoses, fan clutch, etc.
Any ideas?
