Interesting...Never really thought about bump-starting. Immo still has to be disarmed, so it's only a work-around for no-crank and should work provided the "bump" rotates the engine long enough to enable the DME relay.

Ok guys,
Just got home from HHI and went to start car.
Car started just fine, then I moved R21 to R61 and nothing after turning key to start.
Replaced all modules in fuse box and will wait to start again and take over to my mechanic to see whats wrong???????

By the way Jumper Module that was in R21 looks like module from R61. Gray with 53 on top??

That's strange - CAB's are supposed to have the the jumper module shown in post 6 in relay slot 21. The one with "53" is just another copy of the one in slot R61 - standard N.O. relay. Regardless, the swap you did does rule out the relay so, progress! Jumpering R61 will tell you if the clutch interlock switch is the problem. If you can't finder a jumper module in the fusebox, remove R61 and jumper across terminals 3 and 5 with a short wire (or wrap a bare wire across R61 terminals 3 and 5 and plug it back in).

Question though...what did you do to get it started?
Are you sure the immobilizer is disarmed? (When you turn the key ON, the light in the 4-o'clock position in the clock should stay on for only a few seconds. If it stays on longer, the immo is armed and the car won't crank.

BTW, a regular "53" in slot 21 is fine, it just means the top won't operate unless the key is ON. A jumper in R21 will let you run the top without the key ON.
