i have 2 90 xjs. one i just got running yesterday....fuel pump issues today the other craps out. started fine, pulled forward, shut off for a while came back to leave in it....no start. sputters a little, fires once in a while, wont run. i tested cps on the running one and it show OL on the digital meter. tested the non-running one and it shows 194 ohms. im fairly certain thats the issue but dont know the proper range. (fuel pressure 39 psi so ruled it out) has spark sometimes but not consistant. i searched and found how to replace it but not how to test it besides unplug and replug .....i did this but still no start. thanks in advance!
