Post subject: | Major issues and in need of major advice |
Hi guys After a disaster about two years back and a melted piston I've recently installed a rebuilt engine. Just finished it today and it cranks but won't start. There is no spark at the main ht lead from the coil and the tachometer does not move on cranking I have also replaced some plugs on the engine loom at the same time so as you can imagine I'm in a pickle , any help pointers and advice would be greatly appreciated as I'm rapidly llosing my mind and what's left of my hair. Thanks guys Regards Barrie |

If knew what model I could post manuals / circuits to help. It's all controlled by the ECU so you need to check power to the ecu, this is fed via ECU and EFI fuses. A good indication is to link E1 and TE1 in the diagnostic connector and check the engine light flashes. (see gow-to guides -> check error codes from this site front page). Also confirm you have connected the ECU earth eyelet under the inlet manifold. The triggers for spark and injection come from the distributer base - a 4 pin plug. These are NE (like crank sensor) and G1 and G2 (cam sensor). A problem with these will flag a fault code. The ECU then triggers spark with the IGT signal to the igniter which drives the coil. There is an IGF confirmation from the igniter back to the ECU which raises a fault code if missing. I think the RPM meter is also driven from the igniter. |

Also I've replace both the dizzy and the plug by cutting the wires and resoldering and taping up this was before the engine went in so it could be those How can I check those two items without removing the dizzy. : Update is code 14 and 21 which is the oxy sensor and should not make any difference code 14 is the problem any advice guys. Regards Barrie Update : it was a broken wire in the loom that run to the Ecu and ignitor Thanks for the reply Nibbles it was much appreciated and set me in the correct path Kindest Regards Baz |
