1994 Ford Ranger 4.0 cranks runs about 1 to 1 1/2 minute and cuts off.


There are 2 relays in the relay box that could cause this problem the EEC relay and the FUEL pump relay the best test for EEC relay back probe the throttle position sensor for the 5 volts reference signal run engine and watch to see if you lose this voltage. and fuel pump relay install a fuel pressure gauge to fuel rail service port and check to see if pressure drops to zero.

Was running fine on interstate, started losing power on hills, cut off would not restart


When it fails to start-- do you have spark or injector pulse or
fuel pressure-- while cranking--?

Could be a crank sensor --but replacing parts with no testing,
is not the way to go --learn how to test components

Could be a crank sensor failed, fuel pump or timing issue,
chain or belt whatever it has

Look at Professional Scan Tool Data--codes or not, that is
always where you start & check the battery out is always a first
step as well

I have replaced my fuel pump, filter, throttle position sensor, and relay on my 1992 jimmy. it runs but everytime it hits idle speed it cuts off. what could that be


It should have an idle air control valve which lets air into the intake to control the idle speed. The valve could be faulty, or dirty, or the throttle body could be dirty. The computer opens and closes the valve to regulate idle speed.

Van kept surging. would idle real high. then i had to really gas it to get going like thru a stop sign. finally going up a hill chugged for about 2 miles before it just went like it was fine. nest time it...


I'd suspect the ignition module (external, next to the distributor) or the PIP module (inside the distributor) or maybe even both-get Motorcraft parts the aftermarket stuff is mostly hit or miss.

1999 Chevrolet Cavalier, surging, stalling


Check the Alternator, Mine was doing something similar to it, was almost dieing constantly, at stops in drive, lights would flicker alot on bumps and up hills when rpm's would increase. Also yea mine also got worse after it warmed up, I replaced the alt. with a reman. but unless it was professionally rebuilt by a local electrical shop (which are kind of rare now a days) I would just get a new one from a local parts house, Also you pay for what you get. Do not have the shop get the part for you because they have anywhere from a 10%-25% mark up on local parts houses which is close or above what you would pay
