I dropped by the shop that my 14' is having it's repairs/diagnosis done, and they said my car is missing a part that allows the Djet system to operate. They described it as a bunch of resistors enclosed in a metal casing w/ a male connector w/ 6 prongs on the connector. The female connector comes off the FI harness on the passenger side of the engine bay. here's a drawing of the connector since i didnt have my camera on me at the time. If anyone has one please PM me. Thanks in advance

Sounds like an L jet resistor pack. You sure they know what they're doing? You sure your car is a 74 2 litre? The Cap'n

the car is a 74', but the newly acquired engine is out of a 75' w/ a complete Djet FI system w/ the smog items plugged.

Djet did not have resistor packs installed....

so either you have L-jet or you fried your injectors...

D-jet switches the injectors using the hot side
L-jet switches them using ground.

combine them and PSSZZZT.

3.6K Ohm on each resistor. Give me a week and I can Make a resistor pack....

well it aint unheard of.

If you cant find one, i'll make ya one.

its not too hard.

even if you find one with a wire or two gone, i can fix it very easily....

I have no idea....

I broke a wire off of mine and re-soldered it back on...then i tested it with a ohm-meter, and I thought "heh, this is easy...I could actually make one if i needed to."

I imagine PP might have them?

The "D" Jet for a 75 has such a plug, but don't remember if it is that shape. It's for a "fuel cutoff" as far as I can remember....I have two of them (complete harnesses)

But, the canister is not necessary for the car to run.....if it is what I am thinking of.

Find another shop if that's the case.

yes...

please please please find out what it is for sure before you start buying stuff....

L-jet has a funny large black square box off to the left side (from standing at back of car) of the engine...

D-jet has the mps, attached near the battery tray, looks like a silver hand grenade...dont pull the pin, its a very expensive grenade.

L-jet cars have colored connectors with funky pin connectors. D-jet connectors are all white.

please find otu what you have.

If you do have L-jet, i'll make me a custom resistor bank and you can have my OE resistor pack.

does your car start...?

if not, check this out for me.....

make sure the yellow wire is in this position, which is NOT where the wire is now.

it should be in pin II.

yeah but why isnt the system working....?


oh, and my pic assumes you have L-jet. If you have D-jet, that whole plug-in area will be filled with a white plastic connector.

the resistor pinout looks like this:

again this assumes that you have L-jet...

L-Jet cars require the resistor pack at that 6-pole connector.
D-Jet cars have the same connector but its for an optional speed limiter...not required as Ron mentioned. D-Jet cars do not require the resistor pack.

This shop is fine...they do good work, and i'd rather not bypass this doo-hickey.

the system doesnt look tampered w/ and it does have an MPS. And IIRC the L-Jet system doesnt contain the MPS.
