Grommet fell apart... Took it off and attempted putting new in and with help of 3 others got it in still had to cut it and apparently once cutting the grommet you expose the inside of it the gas deteriorates the grommet so took it back out...(never dropped tank...) So boyfriends 98 mustang has been running without a grommet for a while which means yes spilling gas every turn... But anyways, main question im trying to get to the bottom of is the car hesitates to crank 4-7 seconds and occasionally dies, but recanks and its up and going asap. Once driven and shut off, recrank and it starts perfectly. Ive been on other forums and posts about crank issues and this is something new I thought of that I have no idea whether or not itd be an issue. Thought maybe fuel filter may suck in air with gas causing issues but idk... Insight please!? Replaced starter, altenator, fuel filter a while back, radiator, coil pak not too long ago. Its not an engine misfire because I know what that feels like and this is just just a crank hesitation, maybe ignition?
