Will Accel fuel injectors work in a 1990 Allante? If so, can anyone advise me what size/specification injector would be correct?

you want 19 lb/hr injectors for a 5.0L ford mustang

Thanks StickPony, probably next weekend before I'll get to it...............buy I'll repost when I've finished the installation.

People have been having a huge success with the injectors from a Ford 4.6 liter. The ones with orange tops. I have them in both my Cadillacs and seen a performance gain as well as a Fuel Mileage gain.

Lurked around a couple of topics on fuel injectors because it looks like the ones in my 91 DeVille with 203,000 miles on it are toast. My mechanic gave me the bad news today, and I managed to sputter home after stalling at most lights. I had it tuned up right after I bought the car two months ago and it had been running fine until a week ago. Fuel pressure is good as is compression.

Looks like the Bosch sets from fiveomotorsport.com are my best deal (the NAPA store quoted $80 something each and GM Parts Direct are $65 each plus shipping.

How hard a job is it to change out the fuel injectors? I'm no mechanic, but I have a good friend who has helped me work on my 64 Impala, and he's pretty sharp. Are any special tools required? Anything I should know that's not in the shop manuals?

Thanks in advance for the advice.

The bosch ones from five-0-motorsports are the same exact thing as Ford 4.6 injectors as long as they are the orange top ones. I have used two sets so far on two devilles I have and they perform flawlessly. They even go right in like they were made for the car. Just go to the junkyard and get a set from a 91-up Crown Victoria, Town Car, or Grand Marquis. And your all set. They are very easy to change if you have any mechanic experience what so ever. I have mine swapped out in under a hour.

Thanks, Blaze. Under an hour, eh? Considering most times I've worked on my Impala it takes twice as long as it should, I'll be happy with 2-3 hours. Will check out a shop manual at the library tomorrow to get the details.

OK, I'm finally getting around to putting in the new fuel injectors I got from fiveomotorsport. Thanks again to my Dad for paying for them (I'm broke).

I'm hoping this will cure my car's stumbling, lurching and stalling, and the Service Engine Soon Light will quit coming on. I had the engine tuned up in July with new plugs, wires, cap, rotor and fuel filter. Compression and fuel pressure are both good.

There were a bunch of codes when I checked the OBD system, but I'm not sure which ones are current, so I cleared the codes and drove the car for about 10 minutes round trip. The Service Engine Soon Light did come on again, and when I checked for codes again, the only one I got was E41 - Cam Sensor Signal Problem. Could this be related to the bad fuel injectors or is that just wishful thinking on my part?

I'll post again when I get the fuel injectors installed and see how she runs. Thanks again, Blaze, for the tip about Five 0 Motorsport.

BTW, my shop manual says in some cases, you have to remove the power steering pump. It does look tight over there, but I'd like to avoid taking anything apart I don't have to. Blaze, when you swapped out your fuel injectors, did you have to pull the power steering pump?

If your getting the E41, then you need to replace the cam sensor which is also known as a hall effect switch. It causes all the symptoms you described. It controls the fuel delivery so it could make a person think its the fuel injectors.

Do I have to go to a Cadillac dealer for this part or can I get it from GM Parts Direct?

Got the new fuel injectors installed, and in a brief test drive, it looks like the major problem is solved. The car idles smoothly now, and when I stepped on the gas, it took off with no stumbling or lurching. I'll post again after I drive it to work tomorrow (20 miles on a two lane highway, 55-65 most of the way).

You can get it anywhere you can get regular auto parts. I hope the injectors solve your case, but if the code E41 comes up again, you have to replace that sensor.

Well, it looks like I'm not out of the woods yet. I still get the code for the camshaft position sensor, and my car stalled and stumbled a couple of times on the drive to work this morning. It would lose speed, no response when I stepped on the gas, then the engine would die. Rats. I called a couple of auto parts stores, plus the local Cadillac dealer, and the part runs about $125. Fortunately, I found the same part at GM Parts Direct for about $65. But before I order (and I can't do it until payday—Thursday), is it possible that the electrical connections from the sensor just need to be cleaned up? Or is that just wishful thinking?

Its possible, but not likely.

OK, it's been a couple of days since the fuel injector swap. The car does not stall at idle like it did before, but when I'm cruising down the highway, it will suddenly lose power and stall. The only code I get is the E41 for the camshaft position sensor.

I'm ordering the hall effect switch on Thursday (payday). Should that fix the problem?

 

[MusicCity]

It should fix your problem. A nutdriver and some patience helped me swap that sensor out. I would like to hear some advice, if any on the fuel injector swap project.
