Have a 91 sr5 4x4 with a 3.0. Just replaced o-rings on the injectors and drove for about 1.5 days. Now will not start will crank over but no start. Pulled the coil wire and will spark once against the fender but then stop. And idea out there??

 

is it throwing any codes?

 

Get an FSM, start checking things.

"it won't start" is too vague

 

Cap and rotor were shot... Thanks for the replies.

 

Check those plugs and wires too I bet they are bad aswell
