Have a 99 land rover d2 with signs of a ckp failing. When I went to replace the ckp I noticed when hooking the plug into the clip that holds it, that two of the wires on the harness side of the connector had been pulled out of the pins. I de pinned all three wires and repaired them and continued to re plug in the ckp and attempt to start the car. I then had a crank no start. I checked fuses but none had popped. I figured maybe the wires made contact and blew a fuse. After this I cut the connector and a few inches of wires off an old harness we had laying around and just twisted the wires together to give it another attempt before soldering them, thinking maybe the pins were not making good contact and a new plug would fix the issue. I'm assuming I got the two black wires mixed up on the first attempt because I then had no crank at all. I swapped the two black wires, checked fuses again and none had blown. So I attemped again and got a crank no start again. I have no spark and no fuel. Is it a possibility that a blew a relay and not a fuse? Or where should I go next. Thanks

 

1. If signal wires are reversed, timing pulse will be 6 degrees off.

2. No fuse - straight from ECU.

3. ECU can't see 80 rpm when engine cranked, so fuel pump and spark inhibit.

4. Problem lies with CKP spacing and or wiring.

5. Poking around in wire harness does not mean you did not blow a fuse, so may have check every one with a meter, not just the Mark I eyeball, may be a small crack. Also reset the inertia switch just for fun.

6. Here are two sets of pages. The signal wires are black&yellow and pink&black, the ground is solid black. Black /yellow and rink / black will read some sort of continuity going into sensor, it is just a coil of wire. Should not read continuity to ground.

7. It is quite common to get spacers and such mixed up when roving and replacing CKP. Spacing is ultra critical.

 

Turned out to be a relay. Got it all buttoned up this morning in 20 min

 

Thata4t,
Glad you got your problem fixed, but off topic, my cps sensor harness connecter was missing when i bought the car and been looking for that since.
Would you be willing to cut and sell that to me if not needed?
Cps = camshaft sensor in front right above crank. Its a 3 pin connector.
Thanks
Jack

 

Which relay?
