Hard starting
I'm having some summertime blues. 1998 2.5 is hard to start in hot weather after running about 40 miles or so then shutting it off. Get back in after 15 minutes and the beast won't catch. I have to crank it several times and pump the accelerator to get it to start. By cranking, I mean turn the key and hold for a couple of seconds then turn it off and repeat until it fires. Any ideas what to look for?

Possible fuel pressure issue (pump, pressure regulator). Try running the car with a fuel pressure test gauge attached to the test port on the fuel rail to see if the system is losing pressure. Another perennial favorite is the crank position sensor, which can act up when hot, causing the DME to turn off the fuel pump. You can test the CPS:
1. Connect ohmmeter connector part to rpm/crankshaft position sensor, pins 1 and 2. Display at 20 °C: 0.8 – 1.0 k Ohms 2. Connect ohmmeter connector part to rpm/crankshaft position sensor, pins 1 and 3. Display: infinite ohms |
Thanks
I'll give it a try |
