sergio620 Posted July 22, 2017 Report Share Posted July 22, 2017 Hello I have a 1979 620 l20b I turned it on after driving and it was bogging and wouldn't accelerate then it stalled out. Then I would try to start it again yet it would only crank but wouldn't turn on any input? Ignition coil? It's running a Mallory ignition coil btw Thanks in advance Quote Link to comment
datzenmike Posted July 22, 2017 Report Share Posted July 22, 2017 You need gas and spark to run.... I hate after market crap that used to have a reputation. The only coil made for your year truck is the one from Nissan. That 'Mallory' coil might be intended for a distributor with points. The high power Electric Ignition you have in your '79 will over heat and fry a points coil. Pull a spark plug wire off and stick an old plug in the end. Lay on a grounded surface and crank the engine over. Got spark? If yes I'll assume it's alright for now, and say there is a fuel problem. If no/not sure, put your good original coil back in. 1 Quote Link to comment
LenRobertson Posted July 22, 2017 Report Share Posted July 22, 2017 This thread concerns a B210, but a lot of the ideas for trouble shooting will apply to your truck. http://community.ratsun.net/topic/72362-79-b210-wont-start/ As datzenmike says, check for spark using a plug. If you have good spark, then on to checking fuel issues. See if you can narrow your problem down a little using info in the B210 thread, then we may be able to help with more specific things.

ratsun.818 Posted August 2, 2017 Report Share Posted August 2, 2017 Check for spark if any. If it's fuel related it might be your fuel pump m8 I've ran into this before as well Quote Link to comment
