hello, i got a jeep that cranks over for a while before starting up. it also has a wierd smell after the engin gets hot. i know that the engine is old but i would like to know what could help. thanks.

 

Wierd smell? could you be a little more descriptive? Rotten eggs? burnt plastic? sulfer?

As for the long cranks, it's normal for jeeps to take a second or two cranking before there's enough fuel pressure in the rail. How long is it taking?

 

well its cranking for a good 5-9 secs. i have already replaced the fuel pump but it hasnt fixed the cranking. as for the smell its kinda sweet, i would say... could it be anti-freeze or coolant?

 

long crank is normal for a renix. Should be ~10 seconds or less. It has a couple more things it has to search for before it fires, unlike HOs.

Here are my old 89, and my new 89:

Turn the key to "run" and let the fuel pump run, wait 5 seconds. Then start it.
You should do this with any vehicle, but it really helps with jeeps.

 

Poor/low CPS output voltage can cause even longer crank times in a Renix than is normal. Got a voltmeter with a scale for AC volts? It's easy to test.

 

i dont know where to post this question, so im gonna ask it here instead of opening another thread.. but, what welding machine would be considered bare minimum for welding onto the chassis or axle?
