First thing to check is the fuel pump relay. If you squirt a little
fuel down the injector and it wants to start thats probably what it is.
For my 89 its located on the driver side fender well. Cost $10.00.
On the 99 it will be in the underhood relay center along with the pump
fuse. There is also a way to jumper power directly to the pump. I would
do that first to see what happens.
The problem could be the pump fuse,relay,wiring or the pump itself. If
it is the pump then you will also want to change the connector on the
harness as well.
It is also possible that the crank sensor or cam sensor could have
failed. If either one fails it will cause a no-start.
Steve, you seem like you know these well. What would be your thoughts
Same S-10 4 cyl. It sometimes hesitates and coughs on acceleration like
the older engines with carburetors would do when the accelerator pump in
the carb was bad. Runs like a dream on freeways, only problem is when I
need sudden acceleration. TIA
When was the last injector cleaning? Tune up with GOOD plugs?
Last 2.2 in here that acted that way had a weak fuel pressure regulator
and plugs with about 150K on them.
I would check the fuel pressure under actual conditions, check the TPS
for good tracking and run a cleaner through it.
Injector cleaned, new plugs (passed smog with low numbers). Haven't
checked the regulator but it seems to get plenty of fuel at high RPM's.
Turns out the counter guy at the local Auto Zone is an S-10 junkie. He
suggested the TPS also. Thanks.
