TRUCK WONT CRANK AFTER MOTOR SWAP

1997 Dodge Dakota • 110,000 miles

We recently purchaced a totaled 98 dokota with v6 and auto transmission. After swapping motors, trannys, and all wiring, into a 97 dodge dakota, that was a standard with a 4 cylinder, the truck will not even turn over. It makes a clicking sound from either a relay or solonide. We did here the new motor run before we made the swap. Any suggestions?

It may be wired the same but where it connects to the piece going in the truck may be different. But going from a 4 to a 6 you neeed to also change the computer as there may be a big differnece there, especially to make it run.

Pick your symptoms below check it and get back with some testing results

**Cranks but no start condition: Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

**No crank at all/nothing/nada when key is engage to starting position

Could be a blown fusible link, the starter, starter relay, clutch switch/park and neutral switch/transmission position switch and ignition switch assuming the battery condition and connections are good. Note: If it doesn't apply disregard.
