Customer Question

I have a 90 Chrysler New Yorker Fifth ave. with a 3.3L I've rebuilt the engine and I'm trying to replace the Auto shutdown relay but can't find it. It's not where the Haynes books says..
JA: Sometimes things that you think will be really complicated end up being easy to fix with a Chrysler New Yorker. The Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: It had an over heat problem. I have the heads done then it lost oil on the back head. The problem was cam bearings so I decided to rebuild the engine. I had to replace everything but the pistons and rods! All sensors have been replaced as the computer. It cranks but will not start, I've lost spark. I've found no broken wires or bad connectors.
JA: Are you hoping to fix this yourself?
Customer: I had it to, and your not going to believe this, to a dealer! 4 weeks and $846 later, they could not get it to run so yes.
JA: Is there anything else important you think the Mechanic should know about your Chrysler New Yorker?
Customer: Not right now, he can ask anything from here.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer where you can place your fully refundable $5 deposit (plus $19 after the Mechanic responds). While you're filling out that form, I'll tell the Mechanic about your situation and connect you two.

HI,

It should be in the same relay box as the ac compressor relay and radiator fan relay -see attached

Customer: replied 9 months ago.
It's not
Expert:  Eric replied 9 months ago.

HI,

Ok, is there an empty cavity there for it? If so, it is possible it was removed and not replaced

Expert:  Eric replied 9 months ago.

HI,

If not, then please post the full vin number and I will pull it from that

Customer: replied 9 months ago.
There are no empty places or wires I can find: 1c3xy66r6ld854220
Expert:  Eric replied 9 months ago.

HI,

Hmm, pulling the location by the VIN number shows same location. I will opt out and see if another expert knows of an alternate location it would be at

Customer: replied 9 months ago.
OK, the Haynes book shows it above the engine computer but all that is there is the starter relay. I can't find it anywhere
Customer: replied 9 months ago.
don't know if replacing the ASD relay will make it fire up.
Expert:  Mike S. replied 9 months ago.

I see it in the power distribution block.

Expert:  Mike S. replied 9 months ago.

There is also something called a safety shutdown relay and it is located on the right fender panel. Neither of these 2 spots from what I can see is the same spot as the starter relay, cause that is on the left strut housing.

Expert:  Mike S. replied 9 months ago.

There obviously is a mix up somewhere cause someone else is asking the very same question:

Here is the location on the 1989 Chrysler New Yorker 3.0L Eng Base

Expert:  Mike S. replied 9 months ago.

Find it yet?

Customer: replied 9 months ago.

No I have not found it and I have replaced the coil pack and computer this morning per the tech I talked to yesterday, still no fire. Now what?

Expert:  Mike S. replied 9 months ago.

Which tech. not me. I don't remember saying to replace the coil pack.

Customer: replied 9 months ago.

I don't remember his name, It was a phone call to me.

I just don't know what to check now. By all respects it should run

Expert:  Mike S. replied 9 months ago.

The PCM supplies battery voltage to the ignition coil through the Auto Shutdown (ASD) relay. I know now why you were searching for it. So, do you have voltage to the coil pack with the key on run and start?

Expert:  Mike S. replied 9 months ago.

Then if yes, perform this no-start test checks the camshaft position sensor and the crankshaft position sensor, under the 3.3L and 3.8L Engines

Expert:  Mike S. replied 9 months ago.

During cranking, the ASD relay will not energize until the PCM receives a crankshaft signal. Because of this I suspect a crank sensor circuit fault.

Customer: replied 9 months ago.

There is no voltage at the coil. Both the crank and cam sensors have been replace by a deal.

Expert:  Mike S. replied 9 months ago.

Well, if there is no voltage going to the coil, it's obvious a new coil isn't going to fix the problem.

Have you found the Auto shutdown relay yet?

If so, check it for voltage when the engine is cranking or just find the pin at the PCM that it is supposed to supply, while cranking.

Also, it might help to know any codes if the check engine light is remaining on past bulb check and if there is any security or anti-theft lights or messages on or flashing?

Plus the vin, to doublecheck this.
