I have a problem with my ´73 2.0 with the original fuel injection that drives me crazy!
I have completely overhauled the engine. After putting it back in I can not get it to start with the starter motor. The motor crancks but it will not start. When I pull it with another car it will start instantly. Using jumper cables from a car that is running at 3500 rpm does not help. Here is what I have done so far: Replaced the battery with a new one; Checked all the wires and connections, everything is set up correctly and the connectors are all oke, I´ve used contactspray on all contacts; Replaced the spark plugs with new ones, left the new ones in, put the old ones in the caps and crancked the engine, all spark plugs give a good fat spark; Set the timing; Replaced the starter motor with a different one; Checked the ground strap from the gearbox the the chassis; Attached a starter cable from the gearbox directly onto the negative lead off the battery to elimanate ground strap problems; Checked the fuel injectors, they all inject fuel when the enige is crancked; Put in fresh new fuel; Airfilter is new; I really don´t know what else to try. When the engine runs, it runs perfectly, very strong, no smoke, no misfires, no strange noises. When I switch it of warm it also refuses to be started in the conventional way. I really don´t know what else to look for, it drives me crazy! (IMG:style_emoticons/default/headbang.gif) Anybody have an idea of what I can/should look for? Frank |

The motor crancks but it will not start. When I pull it with another car it will start instantly. I'm struggling with a similar problem. Even when the car is warm starting is difficult. Not impossible - just difficult. It will catch after a bunch of cranking sort of one cylinder at a time. When it catches on all four it then runs great. Fuel is there, spark is there, so the only thing really left is timing? Advance not working right? or perhaps something special about the mix that happens only when cranking? I don't have the answers yet but I'll follow your thread with interest. |

The old one (which I assumed to be an original black bosch) turned out to be something called American Standard Auto. When you shake it it rattles! (IMG:style_emoticons/default/blink.gif) |
