1999 audi a4 not starting, healthy swing , got spark.auto elec mate took look said no power on fuse 28(fuel pump) and fuse 29 (engine management). where do i locate the relays for the engine management system and the fuel pump to check if theyre fried?

The fuel pump fuse is located in the engine bay fuse box. It is the 2nd row from the top, last fuse on the left.

Ck the fuses here is the info if you already haven't.
1-Headlight washer jets
2-Turn signal flasher
3-Headlight washer, glove box light, engine bay light, instrument cluster
4-License plate lights
5-Instrument cluster, heated seats, auto trans display, outside air temp
6-Central locking system
7-ABS
8-empty
9-heated mirrors
10-empty
11-cruise control(auto trans)
12-on board diagnostic system
13-brake lights
14-interior lights
15-power windows, climate control
16-ABS, anti-slip(?)
17-heated door locks
18-right high beam
19-left high beam
20-right low beam
21-left low beam
22-tail and side marker (right)
23-tail and side marker (left)
24-wipers and washer jets
25-blower for heating/climate control
26-rear window defogger
27-empty
28-fuel pump
29-engine timing
30-sunroof
31-tail lights, cruise control, auto trans
32-engine timing
33-cig lighter
34-engine timing
35-trailer receptacle(?)
36-fog lights
37-radio
38-trunk light, central locking system
39-flashers
40-horn
41-empty
42-empty
43-heated seats

Ok there's the numbers. To figure out what the hell that means you have to look at the inside of the cover to the fuse box. left side of dash panel. Good luck.

hi
have you check the starter motor. it might be stuck.

Sounds like you have either a shorted fuel pump driver ground or a sticking fuel injector or injectors. Remove the injector electrical plugs and see if it still flood if it does then then one or more injectors are defective, if not then the engine wiring harness is grounded to one or more injectors or the PCM (powertrain control module) is defective. Remove the spark plugs to ID which cylinder is defective, disable the ignition system when you do this or the gas squirting out the spark plug hole can ignite (been there)

This is where it would be nice to plug it into a code reader, but lets go over some probabilities. Did you check to see if the immobiliser is active ? Fuse 28 (fuel) and 29 (ignition) are fed by the same ECU output. Check them. Fuel pump relay is #208 .Check. Also, the Passat has a strange quirk, where it has 2 temp sensors. The ECU checks both and if there is a discrepancy, it wont start. Start with this and good luck.

have you check fuel pump fuses and relay when you turn key do you hear pump did you bleed air out of fuel lines after pump replacement is it getting spark to plugs when the car died the first time how did it die were you driveing it was there any check engine lights on

mcdevito75 here, The electric fuel pump in the gas tank may be stuck, try rocking the car side to side with your hip to loose the float arm, Check fuse too, even try turning the key on / off a few times to get the fuel pump going.

Have you checked to see if there is spark at the plugs? If not, simply take out 1 plug (can be any one of them), connect the plug wire to it and just let the threads of the plug rest anywhere on the engine block. Have someone turn the motor over while you are looking at the gap on the spark plug. If your distributor is sending sufficient power, you should see a nice healthy spark! If no spark, then your problem is either bad coil, bad distributor, distributor cap, rotor, or ignition. But first things first, check to see if you are getting spark.

the fuel pump fuse is number 28 and it a 20 amp if that helps
