Mustang is hard starting after sittilng for a while. I have replaced the upper intake manifold gasket. The fuel pump seems to run fine, but it does not build pressure until you manage to get it running. But when the pump runs I can hear fuel running back into tank. Once you get it running, it runs great and has good fuel pressure. Any ideas?
SOURCE: fuel pump location and replacement
You are looking for the constant control relay module- ( CCRM ) see below. The pump will be located inside the fuel tank.Most of the time , its the pump and not the relay but, it wouldn't hurt to check the relay out. Teh relay is housed in the CCRM. Its located behind the engine coolant reservoir.
SOURCE: my 98 mustang wants to start hard
what do you mean start hard?
you mean slow cranking or long cranking before start?
SOURCE: My 1998 ford mustang v6 3.8l .. is hard to start
So what you saying is it's hard to start cold right? Something in computer system not allowing excess fuel to injectors when cold. Probably sensor Get auto electrician to sort it out otherwise you end up replacing things that there is nothing wrong with They got the right gear
SOURCE: my 96 mustang gt 4.6L automatic is running like
vacuum leak. it wiil cause a misfire code to be set because too lean from vacuum leak.
SOURCE: 1965 Mustang 289 2v 2100 carb. The car runs fine
It sounds like the choke may not be opening completely. Check the choke tube from the choke assy. to the exaust manifold. The tube often breaks off at the manifold. There was a repair kit from a co.
called toke.(it was the 60's)The part# was ux-1 it had a new copper tube+sleeve and a fitting, that you would place over the broken piece in the manifold tap
it with a hammer and it knocks out the old + installs
the new fitting. Push in the new tube and install the
other end into choke assy. If it's an elec.choke check
the voltage at the wire to the choke assy. it should be between 7-12 volts, if not check for a fuse in line or at
the fuse block. I don't recall exactly where it is. But if
neccesery you can run a new wire with a 20amp in
line fuse, from the choke plug to the S(stator)connection on the alternator. This will provide enough
juice to expand the bimetal spring in the choke housing. And only when it's needed. When the engine is running..Also the choke can be adjusted
whether it's the tube or elec. You can adjust the choke spring by turning the black plastic cover.
There should be 2 arrows pointing clockwise+counter
clockwise. After the choke is fixed you can fine tune
it by loosining the 3 screws and turning to rich or lean as needed. Hope this helps.
