Pete M Posted April 4, 2018 Share Posted April 4, 2018 starting fluid? for a fuel injection? that is indeed weird. how long do you let it crank before resorting to this? Link to comment Share on other sites More sharing options...
carnuck Posted April 4, 2018 Share Posted April 4, 2018 Try jumper cables and see if it cranks faster and starts without a jump. My fuel pump relay go weak and wouldn’t latch while cranking due to a low battery (one cell was gone but the motor was so low compression that it spun over like it was going to start)Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
