1994 volvo 850 won't start
Right hear we go, Have taken car to a local mechanic (the same guy who fitted the replacement engine after the head gasket blew) so far he has fitted 3crank sensors 2 ignition ecu's 1 fuel ecu and 1 abs ecu he has also spent numerous hours tracing the wiring trying to find a fault. The sum total of which is the ecu even after being resetstill shows a crank sensor error after the engine has been turned over oh and no spark and no pulse to injectors. AAAAAAAAARRRRRRGGGGHHHH!!!!![:@][:'(]
I hate to say, but if I were you I would leave the mechanic for good. He seems to be replacing electronic components randomly, and going through 3 crank sensors, 2 ignition ECUs, 1 engine control ECU (fuel control), and one ABS ECU is just outrageously unacceptable, he should reimburse some of the costs you had to pay to him; he obviously has not caught up with the basics in modern vehicles' electronic systems and seriously needs to do his homework.
BTW, "lol" also looks like someone is pointing a gun and he/she has the arms in the air[8D].

Hi JPN all of the sensors and ecu's have been supplied on the basis of if it fixes the fault i will be charged for it if it doesn't the units are returned at no expense to myself. Sorry for any misunderstanding.
somthing to do with the 5volt pulse from thr ECU to the coill pack (intermittant)
He introduced a manual 5 volt pulse to get the engin started, ran it for a hour and now it starts every time
