Re: Hard Starting - Where to go now?

Dear Mark:

Given the electric pump, what is needed here is a step by step approach to isolate what system is causing the problem.

1) Get the car into a no start situation.

2) Pump the accelerator a few times and check for fuel. Using a squirt oil can squirt some gas down the carburetor. That will isolate a fuel delivery problem.

3) Using a KD Tools spark tester set to 20Kv (available from NAPA) and connected to ground; check the ignition. You should have a good strong spark.

4) With the motor hot pull a plug and using a screw in compression tester crank the motor with the throttle wide open. If the compression is well below 100 that may be a problem. If the cranking speed is slow that is also a problem.

Hope this helps.
