Aamco sabotage?

My ford escort is a piece of shi#.

I took it to aamco to get a free diagnostics, thinking that I can get a mechanic to tell me once and for all, what the hell was wrong.

this mornning the car started after 4 tries, and ran pretty good on the freeway, although I was loosing power at like 75 mph, I would downshift to 4th, and pick right back up, rough idle at the lights, but ok.

after AAmco tells me that the problem with the car was no fuel getting to the engine, the fuel pump was bad, or the electrical leading to the pump is the problem. Even though it was the first thing I replaced.

So I go home take the thing out to check it, I adjusted a loose part of the pump, put it back in, traced the wires to underneath my driver saet, im assuming is the prm, looked fine, went to the engine took out the fuel filter, that was ok, BUT NOW, I CAN'T GO PAST 15MPH! IT STAYRTS RIGHT UP NOW THOUGH, BUT I CAN'T EVEN GO THE NEIGHBORHOOD SPEED LIMIT! AND WHEN I REV IT, AND PUSH THE PEDAL TO THE FLOOR, IT LOOSES ALL POWER!

SOOO! My questions are these:

1. Can a person looking at an engine, do anything to make it not run like mine

2. What the hell is wrong with this car!

come on guys help me! I read all the kudos, see the rep points be given, why can't this escort get fixed!

oh yea, new wires, oil change, pvc valve
along with the new o2 sensor

Did you say you did replace the pump?
IF so what brand?
Is the pump still within pressure specs?
Can you check fuel pressure whle the problem is happening?

Steve,
Its time to be brutally honest about some things. And if it puts me in a jam in this forum then so be it.

1.I understand you are very frustrated w/ you car, but there is no need to be insulting.

2. I don't think you realize just how difficult it can be to attempt to diagnose a car over the internet or any other way for that matter. Unless a qualified tech is standing in front of that vehicle w/ test equipment in hand, all we have is experience and gut instinct as to what the issue may or may not be!

3. Its too easy to blame someone who has recently looked at your vehicle that they may have sabotaged it to try and scam your business. Heres what makes more sense to me. You removed the fuel pump. You reassembled it. You now have a symptom that is worse than the original issue. Logic now dictates 2 things. A. You may not have reassembled it correctly or b. Your getting very close to the original issue (which makes more sense to me)

4. Escorts had an issue with the fuel pump/sender assy, the wiring would short (power side) or the ground would loosen causing some of the symptoms you are experiencing. There is also a "jumper harness" sold by ford that address's part of this issue and I would double check the work AND inspect the sender/fuel pump mounting assy wiring for loose connections etc. Verifiy the ground for the fuel pump, you may need electrical test equipment to do that. Verify you have AT LEAST battery voltage at the fuel pump with the key on engine off.

5. Allot of us here are professional technicians and business owners. Some are pretty darn smart DIYer's

Enough said,

chris

Power Test:
1. Disconnect harness from f/p assy
2. Dvom set to 12v dc
3. Red lead to f/p power @ f/p harness
4. Black lead to a good ground
5. Cycle key to on
6. Observe voltage reading as f/p relay goes on then off
7. You may need to run this test a few times for an accurate reading or have someone else operate the key for you.
8. Test battery voltage @ battery
9. There should be NO MORE that a half a volt (.5 vdc) difference between the f/p harness and the battery.

Steve,
7.6 @ the f/p is a possibility, but 26+ vdc@ the battery is not even close. Check your meter and connections. Battery volts should be 12+ volts w/ key on engine off
