Trouble starting engine, but works after 30 minutes First off my car is a 2000 Honda Civic ex DOHC 1.6 with 205,xxx miles and I've recently had this problem starting my engine after I turned it off and quickly came back to (got lunch). The car usually starts after a 30 minute break. One of my buddies dad told me a fuse might be overheating when I run the car to its stable temp.. The engine cranks up sluggishly but run fines after its started. I replaced the spark plug wires about 2 years ago. Any ideas on what could be a factor? Also, my DLC cable to pull codes does not work. My CEL is on but I have no ways to pull codes. Any advice would be greatly appreciated |

Do you want to figure out the issue for sure, or do you want to try throwing a part or two at it? Elaborate. What does it do or not do? The DLC connector has a pin jammed in there so I will need to get it replaced. I took it petboys for a free scan but couldn't establish a link to the computer. |

I wouldn't mind throwing some new parts in there if it isn't too expensive. http://www.almutmar.com/alimage/jima..._magics578.jpg I see an ECT sensor. The coolant temp sensor for the computer. 2 wire sensor near or under the distributor. Or a main relay, or an ignition switch..... but my nickel bet is on the ECT sensor. You really need to get codes before blindly firing the parts cannon at the symptom, because actually figuring out what the computer already knows will probably save a bunch of time and loot. Handy pic of a parts cannon for reference: Attachment 114016 Oh hell, may as well throw this one in too: http://cdn.meme.am/instances/500x/59320340.jpg LOL I did some research on it. Could the fuse I'm talking about be the PGM FI fuse? One of my buddies dad told me a fuse might be overheating when I run the car to its stable temp.. The DLC connector has a pin jammed in there so I will need to get it replaced. I took it petboys for a free scan but couldn't establish a link to the computer. OMFG LOL Well, at least it should be an easy fix to splice another plug in from a salvage yard car. |

I'm just gonna forget I even read this. You mean like someones code reader broke a pin off in your connector?

Re: Trouble starting engine, but works after 30 minutes im assuming youve checked for rusted out starter connections and battery connections ? these can cause intermitent starting issues and the slugish turnover of the engine leads me to believe it is a corroded wire or overheating wire. |
Re: Trouble starting engine, but works after 30 minutes The engine cranks up sluggishly Is the electric starter is having trouble, or is it cranking the engine ok? |

I guess I too should ask, does this line mean it cranks just fine but will not start and run on its own? Is the electric starter is having trouble, or is it cranking the engine ok? |

Re: Trouble starting engine, but works after 30 minutes SMH. but I have to wait roughly 30 minutes |
Re: Trouble starting engine, but works after 30 minutes i would but I'm not too sure on how to upload a video on here. |

Re: Trouble starting engine, but works after 30 minutes Ok that's a whole lot different than what I had in my head when I read the other posts. Looks like extremely slow cranking speed....and it looks like the dash lights went dim or dark during cranking. Electrical. Battery weak, starter drawing too many amps, or poor connections that don't allow enough current flow to operate the starter. Further testing required. I'd get it to act up then probably do a load test on the battery, And an amp check on the starter, If it's real high it's probably a starter bad,,,, but if it's real low then I'd do voltage drop testing to look for a poor connection or high resistance. |
Re: Trouble starting engine, but works after 30 minutes Battery tested fine with my multimeter. Gas tank half full, having the problem right now but this time the car has sat for a hour and half. No start hard crAnk then clickssssss if I hold it for too long |
Re: Trouble starting engine, but works after 30 minutes Battery tested fine with my multimeter. Need to do a real load test on the battery. Load test using half of the cold cranking amps rating on the label and see if it will deliver that many amps for 15 seconds without going below 9.6v. Then move on to testing the starter. How many amps is it drawing during cranking? Is there any voltage drop in either battery cable to the block or engine? Voltage drops will reduce available battery power to the starter. |
Re: Trouble starting engine, but works after 30 minutes Quick update, I was just getting to the amps of the battery. I had a co worker help me jump start my car. It started up like a champ. So I've come to conclusion that my battery is drained of amps |
Re: Trouble starting engine, but works after 30 minutes Thanks for all the advice guys! I'll post again if I still have issues after a new battery |
Re: Trouble starting engine, but works after 30 minutes Dry solder joint on a relay; opens up when hot. Check fuel pump relay. I had the exact same problem on a 1.6 engine which wouldn't start when hot or after stalling until about 20 mins later. |
