Starting Trouble

got a 91 DA with bad starting…dont know why it wont start…already check for fuel and spark…battery was kinda low to crank but we got around that by using another vehicle battery…it then crank over but didnt start…dont know what else to try???anybody out there with ideas???

have you tried repairing your Main Fuel Relay? i know you said you checked for fuel…
how about have you checked for any blown fuses?
i am by no means a mechanic, sorry, that’s all i can think of…

Make sure your getting a spark on each cylinder

Make sure your getting fuel pressure

Then if it still wont work check the ignition switch as they do tend to go bad where they crank and even start but once you let the key go it shuts off.
