mickyfin32 Posted May 14, 2009 Share Posted May 14, 2009 right i had a mfi engine it was running like a dog so went up country to get me an efi cvh instead with tank conversion n wiring loom n ecu all for 100 not bad got it home had to replace the camshaft sproket was bent so then i worried might have messed internal functions up but no put new one on it turns without scraping or any dodgy noises got the loom in got the tank up connected everything goes to start pump doesn't prime n no spark at front so i find wire coming from petrol tank turns out thats a safety switch the engine is from an orion the switch is usual in the boot so not having the switch on i connect them together n hey presto primes perfect every time ignition is on but still no sprak check fuse's nothing wrong so i wonder then i read on here what it might be crank shaft sensor so i take its out well it snapped so separate box engine drilled it out new one cleaned up fly wheel and tried again nothing n now the pump isnt priming checked the wires nothing has change besides me putting the sensor in so i disconnect the sensor n pump refuses to prime again check fuses n connections n earths nothing.... any ideas or does anyone have a spare loom for a 1.6 efi cvh for mk4 cabby please i think my loom is umm faulty Link to comment Share on other sites More sharing options...
Guest rick76 Posted May 15, 2009 Share Posted May 15, 2009 (edited) hi i had an old 1995 feista 1.4 with PTE engine similar to cvh with similar problems you have after days of messing about i found it was a green relay (though i think its pink on the escorts) above fuse box that had gone i was told this works in conjunction with all the sensors and fuel pump etc? Anyway £12 later all was well again i hope this helps though personally it sounds like a crank sensor issue ie no spark or pump not priming Edited May 15, 2009 by rick76 Link to comment Share on other sites More sharing options...
