Just seeing what people's experiences are with the various options on injectors. In the process of ironing out an annoying issue, and with the car now close to 300,000kms, I think the injectors deserve a look. OEM injectors are no longer available. So options are:
1. Aftermarket injectors - ICON series (PAT) seems to be most readily available. Anyone had experiences with these? 2. OEM Remanufactured (not refurbished) - Seen a couple of shops selling remanufactured Bosch injectors. Cheaper than new aftermarkets. Is this a good idea? 3. Get the current ones serviced - cheapest option, but will it do the same job as a remanufactured? Have heard that if it is leaking, and depending on cause, it may not be servicable and I'd still have to get a replacement. And what kind of $$$ are we looking at for a good service, I've been quoted anywhere from $30 to $70 an injector. Big differences there.

A serviced injector of your own will come back with flow results, you don’t get that with new.

I have a 1997 EL Fairmont Ghia and bought credible new aftermarket injectors and they ran but were over-fuelling, so got the originals refurbished, the car runs like a dream now

The aftermarket ones, were they advertised with the same flow rate? Which brand?

I got them from Bursons, but the mob supplied has gone out of business apparently.
I was quite clear what they were for. The Ghia has the Tickford I6 in it, but the injectors provided were ****e

Get the current ones reconditioned at a credible shop. See if you can find one that does changeover for a core deposit. Means you can do them in your driveway one arvo without losing access to the car for a period.
Or paying someone a ton of cash in labour to do the swap. |

Given the parallel inquiries about fuel pumps and misfiring or stumbling, I believe the OP is fishing for a solution to a more general problem. The only way to quantify the actual injectors as fitted now in relation to this, is to remove them (numbered) and have tested. They might well be fine.

I got my original injectors serviced by a local bloke, did a great job and cost bugger all, cheaper than new ones and work fine

This may be some help ? .....if your going to pull them out just remove the fuel relay out of the fuse box and wind it over to get rid of the pressure in the system

The only issue I'm getting now is extended cranking at start up. 80% of the time it will take 4-6 cranks (used to do it in 1-2), 20% of the time it starts first go. It starts up 100% of the time though. Injectors are next on the list to look at. Given the engine is nearly 300k, they are due for a service regardless anyway. If that doesn't work, its off to the professionals

When I had my EL falcon the injectors were tested and serviced as the engine ran like a pig, had no more problems once done.
Are you sure your injectors are causing problems and nothing else? |

Extended crank can be fuel pressure check valve no longer works properly, you go to ignition, fuel pump pumps fuel to the rail and then it seeps back out of the rail when the pump turns off rather than holding it in the rail - then you get the extended cranking before it fires.
Common problem on Commodore of the same era, not sure if it's part of the pump assembly on Falcons |

Waiting for the mech to come back next week to discuss best option to take. Obviously the extended cranking start hasn't fixed itself over the holiday period.
Have done around 3000kms in the last month, and it doesn't miss a beat when driving. Though monitoring the o2 sensors, it is running on the lean side on both banks, oscillation between 0.1v and 0.6 - 0.7. Just a though, can a dodgy crank angle sensor cause extended cranking, but not affect drivability?

Usually if you got no CKP you won't have spark plugs or injectors firing, if you lose CMP then as an emergency some cars will revert to batch firing the injectors/waste spark ignition. |

Still digging. Serviced injectors didn't do anything. I think we are down to two possibilities, vac leak or timing. It's booked into Ford to get a proper diagnosis in a couple of weeks.
Here is the weird thing. If I pump the brake once, it cranks once 90% of the time then fires up, but firing up isn't always "clean", sometimes coughs and splutters. If I don't pump the brake then it will crank 4 or 5 times. Once it's up and running, it's drives flawless. It's got me stumped.

I should add, i only went to test the brake procedure after I couldn't find a vac leak on all the other hoses. The brake booster hose is the only one that I can't take off as it has tamper proof clip on the back of the manifold.
Lets see what ford comes back with.
