The Odissey continues: Fuel pump for a 1987 Colony Park?

[JesusGM]

Hello Guys!

I posted a thread some time ago about the sudden shut off of my 1987 Mercury Colony Park, specially while the car was in movement...well, I leave the car with my mechanic and the problems on the engine were bigger and bigger, so I take the option of a complete engine adjustment. After 1 month of work and looking for spare parts (not so easy to found in Chile), the car was finished, but it still shut off!!!
Many parts were replaced or repaired, including change of gaskets, IAC Valve, fuel pressure regulator, water pump, etc...

Now, the mechanic says that the fuel pump, which has 14 months of use, has no pressure to work properly. The fuel pump was an "Autobest" found at ebay. This is my last resource to solve this problem, so, if eventually the current fuel pump only has 1 year of life, I want to buy a good one now.
I found the fuel pump with the hanger:

Is "Sprectra Premium" a good maker for this part?, and has this hanger any relation with the fuel level reading?, which is broken on my car too...

My other option is only the fuel pump and strainer, maybe a Bosch?

What do you recommend?. Or of anyone can tell me which is the proper spare part to solve the problem of fuel level reading too...I appreciate your help!!

I have been using the spectra premium one in my 90 for the last year. I haven’t driven the car much but it has worked fine so far. I bought it because it’s the only one that came with the hanger, which I needed due to a very bad fuel tank from sitting ten years. You shouldn’t need the hanger, so you can get just the pump. The Bosch one you listed is a good choice in my opinion.

The fuel lever sender is separate. They are pretty simple things. Maybe just needs a new float or the contacts cleaned. If the circuit board is bad, then you can substitute one from a sedan up to 1989 or so.

I do not believe the fuel hanger for a sedan works on a wagon. I don't believe that part will fit your car correctly, but I do not own a wagon to say this with absolute certainty.

For whatever it may be worth, I fitted a Walbro pump for a Mustang to my original hanger in my 86 Towncar. The Mustang pump is smaller diameter, so it has a hose clamp holding it to the bracket. Its been fine for nearly 10 years now.

Sending unit can usually be cleaned. It has a plastic cover that opens, and inside is a board with a wiper contact hooked to the arm. Carefully clean the corrosion from the board and wiper. Be gentle with the plastic, it gets brittle. If the float is sunk, its a common float used on many Ford products.

Thanks for your advice, guys.
Today the fuel pump was changed, the problem still remain.
The engine shut off when idling, when I stop on a cross or the run is just erratic.
I change many parts, spent a lot of money and feel that I'm giving up with the car .
Probably, if I live in. The States, the problem would be solve now. I don't know what to do...

I reread your original thread on the problem. Seems you have a new Motorcraft IAC which should be okay.

Have you checked for codes? Here’s how: http://www.grandmarq.net/oldfuelinjection/page13.html

I think it would be wise to set the base idle. With the engine warmed up, all accessories off, and the IAC unplugged, set the idle to 750rpm. That sets the base idle. Then plugin you IAC.

Could be many things. Hoping the computer can point us in the correct direction.

has anyone checked the MAP sensor?

[knucklehead0202]

Like the others said, lots of things it could be aside from fuel pump. Could be an issue with ignition, especially TFI or uh, hall-effect sensor? WTF is that thing called?

[gadget73]

the PIP, Profile Ignition Pickup.

Does it produce any codes if you check it with the engine running?

[Lincolnmania]

either that or the map sensor vacuum hose is collapsed or has a hole in it.

Is hard to get a scanner for OBD1 Ford here in Chile, since these cars were not so common at the ī80s. American cars were more popular from the ī70s and before and after that, the japanese and european models rules the market until today.
I order a scanner for Ford models at Amazon:

https://www.amazon.com/gp/product/B000EW0KHW/ref=ppx_od_b_detailpages00?ie=UTF8&psc=1

Anyway, I will try to follow the instructions to scan the computer without the scanner.
For the record, here are the parts that has been replaced for new ones:
-TFI
-ignition coil
-Voltage regulator box
-Spark plug wires
-Spark plugs
-Fuel pump (with tank flush)
-Fuel pump relay
-Fuel filter
-Almost all the engine gaskets
-IAC Valve
-Almost all the hoses of the engine.

And maintenance to almost all other components of the car (water pump, radiator, steering pump, brakes, etc...)
"Check engine" light never turn on, but it does when I turn the key for ignition (like almost every car), after that, it turn off.

[gadget73]

You can use a test light to get codes

http://www.grandmarq.net/oldfuelinjection/page13.html

just count the blinks.

has anyone checked the MAP sensor?

MAP sensor is located on the firewall on the passengerīs side?

If I remember correctly, the hose was replaced recently, but the sensor is the original from the car.

[sly]

double check the hose to make sure nothing has damaged it and that it's still installed. Though the MAP sensors rarely go bad, they do go bad. But do check for codes as that may well let us know what is wrong.

[JesusGM]

I will, thanks!. But I donīt trust on my capability (or my mechanic) to count the flashes So, I will wait the machine I ordered or find another scanner locally.

Besides the MAP sensor, is there another sensor which could cause a similar Symptom? (the engine stop at movement or idling).
If I can. I prefer replace all the sensors that could go bad....after all, most of those parts has more than 32 years!

[gadget73]

The digital display is a nicer way of doing it. I have one myself, but the ABS system in one of my cars won't use it and I don't want to spend the money on the special Ford tester. My solution is a jumper wire and counting the blinks.

Maybe the ignition pickup. They get funny when they start to die. If you can get a complete distributor, that might be easier than just the pickup. The distributor has to be taken apart to get the pickup out.
