2002 Ford Focus Intermittent Cranks but no start condition
Just bought this 2002 Ford Focus with Zetec engine with A/t has 142k
miles. The person had 8 yrs of service records and everything on the car
worked fine. It passed inspection on March 1st. It had 1/4 tank of gas and I
fueled it up on March 4th. Later the next day I drove it home from work
which is literally 3 blocks away and parked it. 5 hrs later it would crank but
not fire up the engine. I had to buy a battery charger to recharge the
battery from trying to get it to start.
So I replaced the 15amp Fuel Pump fuse. The old one had some blackish
color on the blades but I couldn't see any cracks in the fuse. Multimeter
confirmed that the old fuse was fine. Still wouldnt start. I swapped 2 of the
relays for the beam lights and still no start.
I then sprayed starter fluid in the Throttle body and it tried to start up. So I
think I eliminated spark and timing issues.
Today it was 70 degrees out after being 20-45 degrees on last SUnday
when the issue happened. I tried to start it and it actually fired up and
stalled out. I thought it was just leftover starter fluid vapor in the TB. Came
back from my meeting and tried it again out of curiosity and the car fired
up. It did sputter a few times and then the idle recovered and stayed
constant around 750rpm. I let it run and took it for a drive and the gas
pedal was very responsive and the car accelerated just fine. No check
engine light either.
I parked it. Waited an hour and tried starting it again and it fired right up.
Only other issue I am fixing this week is the ignition coil harness plug. The
one wire on the right side was loose and I saw the harness was damaged
and this wire pulled out easily like it wasn't even plugged in. It looks like
someone recrimped the wire and just shoved it in the harness. I used
needle nose to hold the blade in when I pushed it back on and it was tight
and isn't loose like before. I believe this wire controls spark timing on 2 of
the coils. I fixed this before recharging the battery and using the starter
fluid. So the crank no start condition was still happening.
Only other possibility is the gas station I work at has bad gas and had water
in it and it froze the lines up and finally melted today. Hence maybe the
sputtering when it first fired up today.
I will say I got gas for my Ford Ranger XLT at this same gas station last
month and then the truck started experiencing power and acceleration
issues. Now the starter on it isn't working and seems the ring gear has a
dead spot on it now.
I have not checked the fuel pump delivery module or fuel pump yet. It may
be possible either or both are going bad. Not sure how old the fuel pump is.
I have read many posts about Early Ford Focuses having fuel pump
Any thoughts would be appreciated.
You can perform a fuel pressure test to determine if the pump is weak.
