Well, my 2000 ZX3 is back in the shop for what could possibly be it's
5th, that is right, 5th, fuel pump unit... They are already 3 hours
into diagnosing it, and cannot find the exact problem. It started a
week back, driving home, a highhway, starting to go uphill, all of a
sudden, very little power... Downshift from 5th, to 4th, to 3rd...
crawl uphill at 30mph...
Dropped it at my mechanic, not a Ford dealer, he says the error code
reads P0351, the ignition coil pack, so he replaces it. It makes the
car run better, not likely to stall out, idles almost at normal RPM's,
but still fairly rough, and the temp gauge does not go to it's normal
position, about a quarter of the way up the scale.
He cannot figure out what is happening, thinks it is the fuel pump,
which I had suggested to him. Said I should take it back to the dealer,
especially since the fuel pump is under that extended warranty program.
Well I drove it to the dealer, not the one I bought it from, they are
HORRIBLE, so I took it to another Ford dealer. When I drove it out to
them, it was in the same state my mechanic had it, until the last 2 or
3 miles, then it ran normal, but with a check engine light.
I talked to the manager in the service department, they have already 3
hours into diagnosing it, but with no solution yet. Ford suggested to
check the ERG system, check grounds, etc, on top of what I told them
and what the ODB codes tell them.
Anyone have any thoughts? Suggestions?
