Z32 Ignitor Chip interchangibility

[jdm_master_X]

im fixing an ignition problem for my friend and needed to know if the any year J30s or Maximas' would have the same ignitor and harness (assuming that they have VG30DEs). her car is a 1992 Z32 NA. apparently, her car dies intermittently and she needs to wiggle her harness to get it to work again. im guessing that the connection to her ignitor and her harness are bad. so i was going to go to yard to match the part number and pull the part for her. the problem occurs on the passenger side of the vehicle.

the part numbers i came across were refferenced from courtesy nissan. its 22020-00Z32. can anybody at least tell me if i can take the same ignitor and harness from another car?

Not sure if you're talking about the PTU (controls the coil packs firing) or the coil packs (mount on top of each spark plug) themselves. Can you be a little more descriptive on where the part is or what wires were being wiggled? saying "passenger side" is a little vauge.

[jdm_master_X]

the chip that commands the coil packs to fire.

on the link, theres a diagram. its the item labeled "22020N" to the right of the highlighted coil pack (in red).

thats the part i need. so i was wondering if i could go to the junkyard and just pull one off of a J30 or Maxima, or maybe even a Q45.

That would be the PTU...is this what it looks like?

[jdm_master_X]

yup yup. i needed to know if the PTU from a J30 or Maxima is identical to that of a z32 na.

I know it works on both VG30DE and VG30DETT. Not sure abou the other variations of VG30's, but I don't see why not as long as the connectors are the same.

Just FYI, there was a recall on the Z cars back in the day (99 I think) for faulty PTU's. If hers wasn't replaced or fixed under that recall she might be able to get it done for free. There will be a silver sticker on the underside of the hood if it has been done (providing the sticker is still there) or you could call your local Nissan dealer and have them check the VIN to see if its been done. A friend of mine bought a 90 TT last year that never had it replaced and the dealer took care of it for him no problem.

If it's silver then it's the old style, if it's black it's the newer one.

i found recall statements in ALLDATA at school today. i cant give you any scans but i can tell you word for word exactly what the printouts told me: POWER TRANSISTOR: RECALLS CAMPAIGN - IGNITION POWER TRANSISTOR UNITReference: SERVICE CAMPAIGN BULLETIN P4120 Date:October 20, 1994 VOLUNTARY SERVICE CAMPAIGN ON 1990-93 300ZX IGNITION POWER TRANSISTOR UNIT APPLIED MODEL: All 1990-93 300ZX (Z32) AFFECTED VIN RANGE JN1RZ24A*LX000001JN1RZ26A*LX000001JN1CZ24A*LX000001JN1RZ27H*PX000001JN1RZ24H*PX538576JN1RZ26H*PX538160JN1CZ24H*PX536696JN1RZ27H*PX003480 INTRODUCTION An electrical problem in the power transistor unit may cause poor driveability and/or rough idle. A counter measure power transistor unit has been developed to resolve this incident. DEALER RESPONSIBILITY: It is the dealer's responsibility to check each vehicle within the trange of this campaign which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in dealer inventory. SERVICE PROCEDURE: The engine should be "OFF", the parking brake applied and the transmission placed in park (if applicable) before beginning service on the vehicle. 1. Open the hood.2. Remove the air ducting to the throttle body3. Disconnect the power transistor harness connectors.4. Remove the four bolts holding the PTU to the timing belt cover.5. Install the new power transistor bracket.6. Install the new power transistor.7. Connect the power transistor sub harness connectors to the existing engine harness connectors for the old power transistor.8. Secure the harnesses into the clip on the timing belt cover. Tie wrap the other harness to the upper radiator hose. Do not overtighten the tie wrap on radiator hose, as this will restrict coolant flow. 9. Install air duct to throttle body.10. Close the hood.

this we know. Haha, we are trying to find out which model yours is. The recall may have been done by the previous owner, but some were recalled in the beginning and only got the SAME faulty PTU installed as the recall. The rest are the black one as seen above. There is an adapter harness as well on the later recalled units...so maybe look for any extra connectors on that harness.
